I think u have to learn basic computer knowledge.It is very important for everyone.In univercity,I learn a lot of computer knowledge.Maybe it will help me to think about how the computer to run meanwhile help me to program. I think the formal training is important.Just that very basic knowledge.Such as OS,compliter,DS and so on.The newer knowledge,the more change it does.The basic knowledge changes very slowly.I hope it will help you.
