Keeping yourself organized/note taking...

[fish2plus2]

I have two methods of note taking. One is to scribble things inside of a notebook and the other is to scribble things on little pieces of cut up paper at my desk. Both ways, I end up writing the same notes over and over again. I must have wrote: Start stretching in preparation to learn a martial art about a million times.

After I fill up a notebook with my ideas, obvservations, notes, directions, phone numbers, etc... I end up going through it, crossing out the garbage, and then rewriting all of it again in another notebook. It is a huge waste of time.

Any gadgets or systems that you recommend?
