I had gotten to the point where I absolutely refused to 'write' my goals down. Having spent ages usually determining what they are and in the end when I looked back at them I never achieved them they wound up further out of my reach than when I started. Out of sight out of mind. This created the problem also of creating goals for me.
I was challenged by the e-learning course Clear Mind-Bright Future to write them down, when to me writing them down has come to mean losing them. Woke up today with the realisation that I've taken a huge leap toward one of my goals Brilliant!
The way the course is done (at speed) so that you don't really have time to oscillate this course would probably help you over that hurdle. I know only if you're prone to oscillation you need less time to think. Usually after first deciding to do something the more time you have to think the more reason one comes up with not to do it, or why it won't work, or how hard it's going to be.
Most every goal or task I've found it works best if I don't think too much about it.
