Self-motivation to learn.

The idea to this question, dear habrazhiteli, I was given article 30 tips, how to work effectively and not go crazy, working at home
I have long been concerned about the question, how to motivate yourself to learn? How to find the stimulus, the task? How to arrange your own knowledge test?
At the same time, the initial data that learning implies programming training. Just as save yourself from wandering from language to language?
So, given:
How to find an incentive to learn programming?
How to triple test your knowledge yourself?
How to determine the initial direction in learning \ in choosing a programming language?

I would also like to write - that this is a cry from the heart ... It's just a request to give advice. Please prompt.
I would be very happy to note your advice for yourself!
