Reply to How do you finish a production/new track?

I am a long time Traktor Dj and recently started to try and get to grips with ableton for production. The problem I have is I will start a new track, maybe lay down a few drum loops or patterns and fire up a nice bass line and I will save it and come back to it. When I come back to it I always end up changing the original content or believe "hell I dont like that I am staring again". I end up getting half way thorugh a track and then get an idea for something else and start a new trrack. I have about 20 tracks all about half written and I can never seem to finish one.

Any tips for knuckling down and finishing one or is it quite common when you are learning production to keep chopping and changing and starting new tracks without finishing any
