Well,hind-site is hard learned,and we all got it. For the younger guys. put down them cigs,it just gets harder to quit. Take great care of your back,its a weak point of man,once hurt its not the same. Have a job with retirement and insurance,that goodness my wife did,when your young its not so important,but as the time passes it will be. Now some good,get a shop,if you like planes,get one dont wait. Even a 10x12 shed will do for a start. Have some fun when you can,good times are never forgotten. Always keep some kits on hand,you never know when you will need them. RC is a life hobby,you may put it away,but it will come back years latter. Add your wisdom,some young man will be better for it.
