Exercising will make you look better, feel stronger, and fill you with boundless energy. Staying fit will even make you happier.

Leave your ego at the door every morning, and just do some truly great work. Few things will make you feel better than a job brilliantly done.

I get so many big ideas while I'm running and such clarity while I'm lifting weights. And staying fit keeps me happy and positive.

Three hours of focused time on the projects that will really add value and uplift your career are so much better than 10 hours where you are constantly being interrupted and taken off your focus.

Difficult times disrupt your conventional ways of thinking and push you to forge better habits of thought, performance and being.

My best investment, as cliched as this sounds, is the money I've spent developing myself, via books, workshops and coaching. Leadership begins within, and to have a better career, start by building a better you.
