How do you spend most of your day? Are you building some opposites into your free time to keep yourself balanced?
If you're getting where you want to be, your day includes lots of things you enjoy and are good at, so that doesn't mean you should be excluding those activities from your non-work life, but everyone should remember to stretch out into their full spectrum.
Think about your days and what might be under-emphasized in your life.
I'm a software product manager so I spend my workday in email, browsers, instant messenger, one-on-one conversations in my cube explaining software functionality, team meetings, and the occasional presentation to a large group.
What's missing? Being outside. Not sitting. Being away from the Web. Handling physical objects, even paper (other than to-do lists, I mean). Playing. Activities that do not have deadlines. Mental rest. Being aware of my body. Creating something completely under my control. Reading for pleasure. Writing for pleasure.
Right now spend an hour doing something to celebrate your whole self. And listen to your heart, not social norms, when you decide what you most want to do. Play with Legos, break out the crayons and color, start up that D&D campaign, practice some skateboard tricks, launch a kickball league, anything that makes you grin.
