Lessons in Executive Leadership · 02 / 08

Only 3% of a leader's time goes on the thing that matters most.

Module 2 of what an Oxford Executive Leadership programme taught me — and the statistic that stopped me in my tracks.

There's a figure from this module I haven't been able to shake. Researchers estimate that the average leader spends around 3% of their time on envisioning the future and enlisting people in it.

Three percent. On what is arguably the whole job.

The rest disappears into the day-to-day — the meetings, the firefighting, the endless small decisions. And I recognised myself in that number immediately, because the urgent has a way of quietly eating the important. Module 2 was, in a sense, a long argument for protecting that 3% — and then spending it well.

Here's what I took from it.

Vision isn't a poster. It's a direction people can feel.

I used to be slightly cynical about "vision" — it can sound like the stuff that ends up laminated on a wall and ignored. This module reframed it for me. A real vision isn't a slogan; it's a clear answer to where are we going, and why is it worth the effort? Without it, teams get bogged down in the day-to-day and slowly lose their direction — not because they're not working hard, but because nobody's told them what the hard work is for.

The best framing I took away: a vision has to feel realistic and ambitious at the same time. Too safe and no one's inspired. Too fantastical and no one believes it. The craft is holding both.

You deliver everything through other people

Here's the shift that matters most for anyone moving from doing the work to leading it: you don't achieve the vision yourself. You achieve it through your team. Which means the entire game becomes getting people to not just understand what needs doing, but to genuinely want to do it.

That's the difference between people who turn up to do their tasks and people who are bought in. And you can't mandate the second one. It comes from engagement — the unglamorous, relational work of building trust one interaction at a time.

Motivation isn't one-size-fits-all

The module splits motivation into intrinsic (the internal pull — mastery, purpose, the satisfaction of doing something well) and extrinsic (external rewards). The obvious-in-hindsight lesson: different people are driven by different things, and a leader's job is to actually know which is which for each person on the team.

I've caught myself in the past assuming everyone's motivated by what motivates me. They're not. The engineer who lights up at a hard technical problem and the one who thrives on recognition need different things from me — and noticing the difference is most of the job.

Authenticity — and its paradox

The part that surprised me was the "authenticity paradox." We're told to lead authentically — but when you step into a role that's bigger than anything you've done before, "being yourself" is complicated, because you're becoming someone you haven't been yet. Authenticity isn't staying fixed. It's staying honest while you grow into the new version of yourself. That reframe gave me a lot of grace for the discomfort of stretching.

What I'm taking into practice

Protect the 3%. Block the time to lift my head up and ask where we're actually going — then spend the engagement work not broadcasting the vision, but making it something each person can see themselves in.

Next in the series: choosing and connecting — decision-making, and the connective tissue that holds it all together.

Be honest: what percentage of your week actually goes on the big picture versus the day-to-day? I'd love to know I'm not the only one fighting that battle.
