In order to achieve something, anything, you must have a goal.
So the question is "Why are you learning to play?"
1. To enjoy the music.
2. Make your brain work faster. (Yes folks, playing the piano or any musical instruments can make you smarter).
3. To impress you friends when you have the chance.
4. Your personal reason.
You can choose all of the above. Or maybe just one. As long as you have a goal(s), you will see that the motivation will help you out a lot.
