Advice for perfectionists

Question: Do you have any GTD pointers for perfectionists? 

David Allen: Just focus on doing the next action perfectly, which is a lot easier than trying to be perfect about how you approach something bigger. Be as retentive as you want. The only problem is when it stops action. Be a perfectionist about the process, which will require, of course, making decisions on the front end that might not be perfect. Think about what might go wrong if you avoid decisions and action! (If you need a negative motivator.)
