I find the secret to digital - where, you are very right, it can all be altered and redone and redone and redone.... is too not think so hard. do something that you like, take one hard look and say yes thats nice. and then move on. So many pages to be done, so many ideas and thoughts to try on the next layout, and the next layout...

Helps to remember its not a thing you can get 'right or wrong', its just you saving memories for yourself
