Creativity and productivity are quite different. For productivity, you want full alertness. For creativity, you want your mind relaxed. Here are some things that seem to enhance creativity. Except for the first one, they are not in order of importance.
1. Worship the Lord with mind, body and spirit; with both intellect and emotions. Get over your fear of not being respectable.
2. Avoid excess caffeine. It can help you be productive, but not creative.
3. Avoid working with a television on--unless the program is something with relaxing images and sounds, but no narration.
4. Grab and pin down creative ideas when they occur. Carry a pen and a card, or a pocket recorder.
5. Look--really look--at things, at life, at God, at the Bible.
6. Practice. Try being creative. Plan times for creativity, but don't get upset if you're not very creative at those times.
7. Relax. Exercise. Spend time with a pet. Cuddle with your spouse or your child.
8. Expect and accept dry spells. This is easier if you build up a back-log of finished or near-finished creative products, so that you can pull one out when you're feeling dry.
9. When doing something productive, use your breaks as times to be creative.
10. Stop being depressed. Take medicine, if needed. Depressed people sometimes think they're most creative when depressed. That's usually not true.
11. Give glory to God.
"Whether then you eat or you drink or whatever you do, do all to the glory of God."
--1 Corinthians 10:31
