I would say finish university (if you haven't), it should give you good theoretical knowledge in the field you want. Also learn other languages. These are things that are more difficult to learn later. In general, in those years, you should take biggest risks and try to do/learn the most difficult stuff you can find and you are interested in. Do not prematurely tie yourself to a job that doesn't provide a sufficient challenge. (You can always make more money later.) The life is a negotiation with reality about what you can accomplish. Do not set your initial offer too low.
