I look back now and don't know how I found the time. I could only get in the shed every second weekend due to Kids, Golf, ( I do play golf) Auskick footy, and many other commitments. I'm lucky, I have the skills to do a lot of the work. All that work was done for me, not the market, as it should be. There is a Phrase that helps keep me busy, not sure who said it initially. ( He who plans for nothing, gets what he plans for. )
So I would say set some goals, an go for it.

Good luck with your projects.
