Why Your Brain Says “I Can’t Do This”

Have you ever had this happen? You’re having a productive day at work, and then someone makes a small comment about your work or an irritating email pops up… and bam, suddenly you feel unsure of yourself. Or you’ve just hit send on an email when, in your head, doubt already creeps in: maybe you should’ve worded it differently. And there it is — that little voice in your mind: “I’m not doing this right. What am I missing?” It’s fascinating how quickly your sense of competence — that inner feeling of “I’ve got this” — can start to wobble. And all while you rationally know that you’re good at your job. That you’re experienced. That you’ve already achieved plenty. And that’s such a shame, because feeling competent is one of the three core psychological needs we all have as humans. When that need gets poked, we feel it immediately in our body: tension, doubt, perfectionism, or procrastination. It can swirl around in your mind for hours and completely derail your day. Why does this need seem to come under pressure so often at the office? In this blog, I’ll explain exactly why — and share a short exercise to help you handle it more clearly.

At work, you’re constantly being evaluated: by colleagues, managers, deadlines, deliverables, KPIs, Outlook, Slack, and inboxes filled with questions. The workplace is, essentially, one big performance scan for the mind, always checking how “well” we’re doing.

According to Self-Efficacy Theory, our sense of competence comes from four things:

1. Our past successes,
2. Examples of how others do their work,
3. Positive feedback about our abilities,
4. And our stress level.

And that last one is the tricky part. Because when we feel stress — even from something small — the mind often interprets it as a personal failure. “See? You can’t do this.” “Everyone understands this quicker than you.” “You should be doing better.” If you could look at the situation objectively in that moment, you’d clearly see that none of these thoughts are true. They’re simply conditioning — something the Clarity Process explains so well. And the ability to look at your thoughts objectively is something you can absolutely train.

You may recognise a few of these things adults said to you as a child: “Try a bit harder.” “Be strong.”
“There’s no need to make so many mistakes.” “If you do something, do it properly.” Well-intended messages — but your mind drew conclusions from them: that you have to be perfect, mustn’t disappoint others, and should always perform at your best. At work, these old childhood logics get triggered by situations that aren’t actually threatening at all:

➤ A colleague asking critical questions.
➤ A meeting in which you don’t know something yet.
➤ A manager saying something “could be faster.”
➤ An email you can’t answer straight away.

The mind turns that into a reflex of: “I’m not competent enough,” and suddenly you’re experiencing far more stress than the situation warrants.

I recently became a professor and now lead a group of experienced researchers. Not long ago, someone asked me in a meeting: “What vision have you chosen for our team?” I didn’t immediately have an answer I felt happy with, so my brain briefly froze. I felt my shoulders tighten and my breathing become shallow. Luckily, this time I quickly spotted my old reflex — the one that insists I must know everything. But that isn’t a fact; it’s just an interpretation from my mind. I definitely don’t always manage to catch the reflex in the moment, but this time it gave me enough space to take a breath and give an honest reply: “Good question. I actually want to put a bit more of that in writing.” No drama. No panic. The conversation moved on and the tension faded.

Competence Isn’t: KNOWING EVERYTHING.

It’s inner clarity in the moments when you don’t know — or when you doubt.

When you base your sense of competence on external factors — compliments, speed, avoiding mistakes — it will always wobble. But when you see that your mind is simply replaying old scripts, space opens up to respond from calm rather than from old stress reflexes. That’s the power of the Clarity Process I use in my personal coaching: you learn to recognise your own competence separate from outdated expectations and workplace triggers.

A short exercise for the office (or at home):

Step 1 — Notice the moment of doubt.
You usually feel it in your chest, shoulders or stomach.

Step 2 — Internally say one sentence:
“This is just an old memory — not my truth right now.”

Step 3 — Take one slow breath in.
Not to calm yourself, but to become present again.

Step 4 — Ask yourself one simple question:
“What do I need now to move forward?”
A minute to think?
More information?
Asking a question?
Or simply nothing?

You’ll notice the pressure already easing once you see the reflex for what it is.

These patterns are old and firmly rooted.

And if you’d like, I’m happy to help you explore which conditionings still shape your sense of competence — so you can see your own strength far more clearly.

Clarity is trust — renewed every day.
