If you want to learn how to play the Piano, you have to prioritize your Piano lessons more often. Practice playing the Piano frequently. This does not mean that you have to play all day long. Spending at least 30 minutes to 1 hour, 4 to 5 times a week with some piano instruction software as practice session will do just as so you would be reminded everyday on the songs that you’re learning. Also, I would recommend that you focus more on your weak points so that you would know what aspects you still need to work on.  By doing so, I am certain that it no time, your skills can be improved in the soonest possible time.
