If you want to lead a meaning based life, break it up into meaning based units. I got this idea from prolific self-help guru Steve Pavlina and it struck me as very sensible. If you break your life into time based units they have no intrinsic meaning or value. So it becomes both boring and stressful (a lot of modern life if you aren't careful). But break your days into meaning units and it works a lot better. Instead of writing for five hours comeplete something that has meaning (a chapter, a certain number of words, an illustration). You'll be energised at the end instead of feeling stunned. Find out what is meaningful to you, divide up this meaningful task into meaning based units.
