How to learn any programming language?

First, decide which language you will study.

The best method is to code a lot.

Start with basic constructs and write small programs (10 to 30 lines) to test your understanding of the concepts. Stretch yourself, but don't try to run before you can walk.

Programming can be very frustrating, but successfully completing a program can be intensely satisfying and pleasing. Don't give up if you don't understand a concept; programming can be a very abstract thing to learn. When working on a particularly intricate problem, take periodic breaks to let your brain relax and relegate the problem to your subconscious mind. Make a good schedule for working.
