The first filter in deciding where to spend your time is an honest assessment of your ability to practice. If you’re not a natural “practicer,” don’t waste time pursuing a strategy that requires it. You know you won’t be a concert pianist or a point guard in the NBA. That’s not necessarily a bad thing. You’re not doomed to mediocrity. You simply need to pick a life strategy that rewards novelty seeking more than mindless repetition. For example, you might want to be an architect, designer, home builder, computer programmer, entrepreneur, Web site designer, or even doctor.
