It's always good to read about the guys who are making a go of training up as a spark. I'm 36 now myself, but I've been in the game since age 16, I couldn't even begin to think how I would get on if I was just starting what I did 20 years ago. i really take my hat off to you. My advice is take your time and don't ever be afraid to ask questions. The things I was learning 20 years ago are new knowledge to you guys and I always offer advice to anybody willing to listen and learn.
Oh, and the other thing is, it's always been handy to have a trade that can pay cash in hand occasionally!
