it sounds like you are being kind of hard on yourself because you said you waste time either writing on the computer or by hand. i say do whichever is more comfortable. since i wrote my papers by hand when younger i still tend to do that and then type them in. maybe i'll switch some day but i just go with whatever is easier.

here is a mantra for perfectionists: done is better than good. i know, i don't like it either but it's really helpful if your standards are unrealistic.
