How do I force myself to persue a talent I never cared to persue?

I keep trying to figure out what I was meant to do in life and I am just not sure, and I don't know what I am good at.

My mom said when I was a kid I was really good at playing piano, and people were quite impressed, which is strange because I do not recollect a lot of this much, and am surprised.  I feel if I was that good maybe I should take it up again, but how do you take up something that you never cared to persue?

I figure I probably should if I was good at it, but if you have a talent that you never has a passion for, then how do you force yourself to have a drive for it?
