Tips, Tricks & Piano Playin' Resources

Is it realistic for a 17 year old to begin to learn how to play the piano?

I have a keyboard and have taught myself a few tunes on it such as Delta Goodrem- Fragile and Death Cab for Cutie- What Sarah Said
however i would love to learn to play piano properly and wondered if it was a sensible and realistic goal for me to achieve?
(With a piano teacher of course)

In answer to this question of COURSE you can!
I am 17 and a senior in high school, my senior project was playing a song along with my school choir on piano and I did my paper on the effects of music on the human brain, according to my facts music development cannot end until the end of our lives because the part of our brain that attributes music is the same as it does with language, so until we cannot learn to speak or communicate, we cannot stop learning a new instrument, so I say to you go for it! You will be very thankful that you did :)
