I think there are three paths to follow.
Question - where do you want to end up?
2) Pick a language and go through some tutorials. There are tons of stuff on almost every language. Pick one that interests you but stick to something mainstream. This is a good reference to Python for example: http://www.openbookproject.net...
. I recommend something that is cross platform and machine independent.
3) Get an Arduino or Raspberry PI and build something. Flash the lights, read the temp, make the propeller spin, etc.
In any of the above - Have fun and don't make it a chore!
