I understand completely. Until my hubs died everything in my life was compartmented. There were "rules" for everything - I mean, even the toilet paper had to hang a certain way. Now I know better! life is so short and you cant live thinking things can be put off, or youll do things in order, or anything of the sort.
live in the moment - start a million things if you feel the urge, and if you drop dead in the middle, so what - you had the fun of starting them. (I made eggsalad sandwiches for breakfast 2 mornings ago, and had popcorn for supper tonite- lol hubs#2 doesnt care, I fix him whatever he would like, too)
try it on something little, make a mugrug or wallhanging - you'll feel like you did something just wicked ;} - and you'll love it! You'll be suprised how much more creative you'll be once you go with the flow of your mind and heart sharet
