Next time you’re on the bus or taking a shower or any one of a dozen things and places where you can let your mind wander, write down at least three of the things your mind comes up with. I always get interesting ideas while in the shower or waiting for the bus to get me where I’m going. I don’t always write them down. Sometimes I just don’t have pen and paper or I am just too busy once I’m at my destination. I regret it cause the best ideas come when you just let your mind have free reign.
