As it turns out, if you want to be known for that thing you do, you don't have to do it all the time. The best poets, carpenters, leaders, and teachers are also wives, dog walkers, vacationers, and parishioners.
There's more to life than what we do, but we can get caught up so much in our doing that we neglect our being. I often have to keep this at the forefront of my mind, especially as I work on Leadership Does. All of our doing - even doing the important things that leaders must do - is for naught if it's not also making us better people.
Do what you want, but only if it allows you to become who you must.
