Some friends are at the stage that they are wondering, "What now? What's next?" A couple have been fretting on this for a long time but only looking under the odd rock to see if their life purpose could be hiding there.
As my dad once told me, "You'll never figure out what you want to do sitting in that chair. You've got to get out and try things, see what you love and hate, and go from there." Or as the French say, “Bouge Toi!”
As a fashion editor shared when I showed up with a modeling book, a design portfolio, a photography portfolio, and an illustration book hoping she'd help me choose my path, "I won't tell you which to pick, but I can tell you to choose one. Do it till it's not fun anymore, then pick the next thing." She went on, "I'm 35. I've already had 5 careers and hope to have 5 more before I stop." Great advice. I'm doing NONE of those things now--although I've explored them all.
In the same way, it's hard to extend your self knowledge if you are looking each day at the same artifacts of who you are. Get off the chair, get curious, go try something new. Get into motion. You never know what you'll find. Like Doon Wilkins says, "Get stumbling." Expecting to KNOW FOR CERTAIN before exploring, is unrealistic.
Infamous Sun Tzu says, if you don't know yourself, it doesn't matter if you know the terrain and the opponent, you'll lose every time. In this "battle" for purpose for your life, you must know your Self. See him/her through different lenses by thinking AND doing.
Don't wait until you can find "The Perfect Thing". Get in motion toward Some Thing. That way your muscles will be strong and ready to spring when you see the Next Thing. Along the way, you may just find some clues pointing towards Your Thing.
