Trust Your Instinct???

I have a question...

Do you invariably go back to the first way of doing something?

I am trying to write a technical document for work. I am not massively exerienced in this. I have written many couresworks in my time about mathematical things, so one would think I should be quite good at it. It appears I am not! I think its because this is actually about something real, not something contrived for the sake of a grade!

Anyway, the point is this: When I first started putting anything down on paper, I made a good start at describing what I had been investigating. After about 2.5 hours of working on it, I re-read it and decided I didn't think the structure was particularly helpful. So the next day I started again using a different approach. I liked this appraoch but it became a bit too detailed so I tried again, this time starting top-level. It wasn't long before I realised that this method was inadequate as well so I gave up on it for a while to do other things. Today, after about a weeks break, I have had to pick it up again and, re-reading all three attempts, I realised that the first one was the most useful.

Isn't this just so often how it works out? Is this a lesson in trusting my instincts?
