Welcome MickHave built a few dios in the last couple of years, Not up to some standards but I think I'm improving, AND I'm enjoying it!
Enjoyment is THE key of it all. There will always be 'better' builders then you think you are. But it all boils down to having fun with whatever you make. my attempts, whilst could use improvement, have always provided (in the main) enjoyment.
