When Strengths Go Too Far: How to Recognise the Hidden Costs

When does a strength stop feeling like a strength?

For me, it was when self-awareness tipped into self-surveillance.

Self-awareness is my top Realised Strength. It fuels my work as a trainer, strengths coach, and facilitator, helping me show up with curiosity, attunement, and groundedness. But used without balance, this strength can spiral inward into overthinking and second-guessing. Especially when paired with other strong suits like Work Ethic, Pride, and Service, it can become a tangle of over-responsibility.

This overextension can show up in subtle ways:

• I delay taking breaks. Work Ethic fuels the pace, Pride whispers “Do it well,” and Service reminds me, “They’re depending on you.”
• I overanalyse whether I did enough, long after the moment has passed.

Recently, I noticed I was ending the week depleted. Not because my work lacked purpose, but because the very strengths that help me show up so fully for others had begun to drown out my own needs. The strings that once created resonance were now pulled too tight.

Resonance vs. rigidity

Overplaying a strength is like overtightening a guitar string. What once produced a beautiful tone becomes brittle, strained, even sharp. But it’s still a good string. It just needs retuning.

Looking back, I realise how easily this pattern can go unnoticed. From the outside, it often looks like commitment. Like care. Like excellence. And I do value those things deeply. But I’ve also come to see sustainability as just as important. For me, that means noticing when the very things I value begin to erode my wellbeing. 

When these patterns show up in leadership roles, the impact extends beyond the individual. Overused strengths can lead to over-functioning leaders, unspoken dependency in teams, and cultures where responsibility quietly concentrates rather than being shared. Over time, this can reduce team autonomy, dampen initiative, and contribute to quiet disengagement, even while performance appears strong.

In my coaching training with Robert Biswas-Diener, something he said landed with unexpected force: “In coaching, far and away the intervention I do most is getting my clients to use their strengths less.”

At first, I found this surprising. After all, strengths are what we’re good at and what energise us. But the more I reflected, the more sense it made. Many of us in helping roles live deeply from strengths like Empathy, Personal Responsibility, and Service. When these are overused or applied in every situation, they stop supporting us and start running us. Instead of tools we use with intention, they become defaults we can’t put down.

A compass for self-leadership

So I’ve learned to pause and ask myself a few simple but powerful questions:

• Is this energising or exhausting me?
• Am I using this strength to connect, or to control?
• What would it look like to use this more lightly?

These questions have become an internal compass. Gentle, not critical. Helping me check in rather than power through. They bring me back to what I call sustainable self-leadership. That sweet spot where my strengths serve me and others, without tipping into depletion.

I see this often in the practitioners and leaders I work with. People who care deeply, who give generously, and who rarely give themselves the same space to pause. For many, overused strengths don’t show up as burnout at first. They show up as resentment, fatigue, or self-doubt.

And when we trace those feelings back, we often find not a lack of skill, but an overextension of what they’re already good at.

The right strength, at the right time

One of the most useful distinctions in the Strengths Profile framework is this: even our Realised Strengths, the ones we enjoy and use often, need to be used wisely. It’s not about turning them off. It’s about tuning them to the context. The right strength, at the right time, in the right amount.

So I’m learning to catch myself in the moment. To notice when I’ve shifted from reflective to ruminative. From offering support to over-functioning. From being energised by work to quietly eroded by it.

These moments are not failures. They’re signals. A chance to stop and retune.

In coaching, I support clients to notice these patterns and experiment with using their strengths differently, sometimes with less force, sometimes in different combinations, and sometimes by drawing on a quiet Unrealised Strength instead.

What about you?

What is it that you love to do, are good at, and sometimes push just a little too hard?

If you pride yourself on your empathy, reliability, or excellence, try asking: 

Am I dialling this up too high right now?

It’s not about changing who you are. 

It’s about honouring who you are, with more choice and less cost.

That’s what sustainable self-leadership looks like.

Noticing the cost of how your strengths are being used? This is exactly the kind of work I support through individual strengths-based coaching, tailored to your strengths.
