Read everything you can on the subject. In fact, I suggest reading everything you can, period. If your area of expertise is drink coasters, read about cooking steaks or sailing. Expand your mind into other areas. It is never too late and will benefit you and your business.
Life is short.
Keep on learning. I'll be 52 when I'm finished. Stick to the plan you worked so hard to develop and read and learn at every opportunity. Your child deserves it. This site is best viewed at 800 x 600 resolution.
