What do you mean by "computer scientist"? If you want to be a good informatician, you should start laying a foundation of mathematical concepts; read something like Halmos: Naive Set Theory. In parallel, learn some language, maybe something easy like Access, and use it, trying to get a programming context for your mind. When you have been programming for a few months, work through Dijkstra & Feijen: Een methode van programmeren, available in English as A Method of Programming. If this is too hard, you need more mathematics and perhaps more linguistic independence. Dijkstra: A Discipline of Programming is easier to read but is intended for someone further along the road of programming. Do not get caught up with a single language or tool, any more than you would willingly get caught up knowing only one natural language: seek the common principles of programming to implement with any language.
