Find out what is that you want to learn by analyzing yourself that you are naturally skilled/talented at or good.
How to find what I am good at?
1) Look back at your past and see what occasion you were being appreciated or admired by others. And that would be your area of interest, and you can improvise that skill.
2) Check back the time you spent, and you have no idea how much time is being spent. Where time does not bother, or you don't monitor time at all.
3) Separate skill with talent. Skill is what we learn and develop. Talent is what comes by birth. Either skill or talent should fetch us our livelihood.
4) Use what you have already, develop what you have already and Learn that skill which should either help you or others. If your skill has not added anything to your growth, then it's time to look for a new skill.
