The One Skill That Actually Makes You an Adult


There are few skills more valuable today than knowing what you want and being able to communicate it clearly, directly, and tactfully.

Yet most people are terrible at it.

We live in a world where:

• most communication happens through screens
• ChatGPT writes half of our emails and messages
• people sound polished online but freeze in person

Then the moment comes where someone needs to:

• say no
• hold a boundary
• correct someone
• ask for what they actually want

…and suddenly it's like a deer in headlights.

What we're dealing with is not a confidence shortage.

It's a shortage of assertiveness. You recognize it immediately when you see it.

Someone says exactly what they mean without sounding aggressive. They hold their ground without getting defensive. They communicate clearly and people respect them for it.

Most people assume those individuals were born that way.

They weren’t.

Assertiveness is a skill.

And like any skill, it improves with practice.


Why Assertiveness Actually Matters (According to Research)

Assertiveness is not just a communication style. It has measurable effects on mental health, relationships, and professional outcomes.

Research on assertiveness training consistently shows improvements in psychological well-being and interpersonal functioning.

For example:

• A randomized controlled trial with college students found that assertiveness training significantly reduced stress, anxiety, and depression compared to a control group.

• Reviews of assertiveness training programs show consistent improvements in self-esteem, confidence, and social functioning, along with reductions in passive and aggressive communication patterns.

• Assertive communication is also linked to higher relationship satisfaction, largely because people who express needs clearly address problems earlier instead of allowing resentment to accumulate.

The professional benefits are also well documented.

Studies in organizational psychology show that people who communicate assertively tend to receive:

stronger leadership evaluations
higher perceived competence from colleagues and supervisors
better negotiation outcomes
a higher likelihood of promotion

Those promotions, of course, translate to greater long-term earnings and career mobility.

In practical terms, the mechanism is straightforward.

When people are unable to express what they want or need, one of two patterns usually appears:

1. Passive pattern

• avoiding conflict
• hinting instead of saying
• overexplaining instead of asking
• building quiet resentment

2. Delayed explosion

• frustration accumulates
• communication becomes sharper than necessary
• relationships suffer unnecessary damage

Assertiveness prevents both.

It allows problems to be addressed while they are still small, which protects both the relationship and the individual.


The Assertiveness Ladder

Most people try to become assertive by jumping straight to the hardest situations.

That almost always fails.

Assertiveness works the same way exposure therapy works: gradual difficulty.

Start small. Then move up.

Here is a simplified assertiveness hierarchy.


Level 1 — Express Preferences

Low stakes situations where the cost of speaking up is minimal.

Examples:

• “I'd rather go to the Italian place.”
• “I actually prefer the earlier meeting time.”
• “I think option B makes more sense.”

Practice: state one genuine preference per day instead of automatically saying “whatever works.”


Level 2 — Make Small Requests

Begin asking for what you want instead of hoping people guess.

Examples:

• “Could you send that earlier next time?”
• “Can we move that meeting to tomorrow?”
• “Would you mind lowering the music a bit?”

Practice: make 2 to 3 direct requests this week without softening them into hints.


Level 3 — Say No Without Overexplaining

Many people struggle here.

Examples:

• “I can’t make it this time.”
• “I’m not able to take that on right now.”
• “I’m going to pass on that.”

Practice: say no at least once this week using one sentence, without adding a long justification.


Level 4 — State Your Needs

Communicate what helps you function better.

Examples:

• “I need more notice for meetings.”
• “I work best with clear expectations.”
• “I need some time to think before deciding.”

Practice: name one need in real time this week instead of waiting for someone to figure it out.


Level 5 — Address Small Problems Early

Before they become resentment.

Examples:

• “When meetings run late it throws off my schedule.”
• “I felt talked over earlier and wanted to finish my point.”
• “Can we divide the workload differently next time?”

Practice: address one frustration within 24 hours instead of sitting on it.


Level 6 — Hold Boundaries When There Is Pushback

Someone does not like your answer.

Examples:

• “I understand, but my answer is still no.”
• “I hear you, but that doesn’t work for me.”
• “I’m not comfortable with that.”

Practice: repeat your boundary once without changing it just because the other person is uncomfortable.


Level 7 — Initiate Difficult Conversations

The conversations most people avoid.

Examples:

• addressing recurring conflict
• clarifying expectations in a relationship
• discussing unequal workload
• confronting disrespectful behavior

Practice: initiate one conversation you have been postponing, and name the issue directly within the first two minutes.


How to Actually Build Assertiveness

If this skill matters as much as the research suggests, the real question becomes:

Where do you start? 3 practical rules help:

1. Start lower than you think

Jumping straight to confrontation usually backfires. Build the habit with small moments of honesty.

2. Expect discomfort

Assertiveness often feels unnatural at first. That does not mean it is wrong, just new.

3. Confidence follows behavior

Most people wait to feel confident before speaking up when in reality, confidence usually appears after repeated assertive behavior.


A Quick Exercise

Ask yourself two questions this week:

• Where in my life am I currently avoiding saying something small?
• What would the next step up the assertiveness ladder look like?

It might be as simple as:

• stating a preference
• declining a request
• correcting something in real time

Assertiveness rarely begins with a dramatic confrontation.

More often it starts with a small moment where you decide your voice belongs in the conversation.

Performative Living There is a certain type of guy now who reads Jane Eyre in a coffee shop while drinking matcha, not because he likes either, but because he likes what the combination says about him. He wants to be seen as thoughtful, masculine, refined, emotionally literate, and slightly above the culture while still being perfectly of it. That guy is not unique.

A More Useful Way to think about Balance If you are ambitious, driven, and trying to build something meaningful, chances are you have wrestled with the idea of balance. Maybe you have wondered whether you are doing too much. Maybe other people have told you to slow down. Maybe your life has felt intense enough that you have started questioning whether your pace is sustainable, healthy, or wise. But here is something I have noticed repeatedly. The people most concerned about balance are...

KORAB IDRIZI PhD Candidate & Mental Coach The Region Beta Paradox (why tolerable is often worse than terrible) Most people assume they'll change when things get bad enough. Sometimes they do, but more often, they stay, because the situation still functions well enough to continue. Nothing's fully broken, so nothing feels urgent. That middle zone is where a lot of time time gets wasted Psychologists call this the region beta paradox: we recover faster from genuinely bad experiences than from...
