Ever become so absorbed in a hobby that you lose track of time? That's a good thing! Whether you knit, write sci fi, garden, or work on your car, you should spend time on things that keep your full interest. When you're “in the zone,” your mind doesn't churn, you feel more sure of yourself, and you aren't as afraid of taking risks. Make time to do what you love, and you'll also give your life more meaning.
