How can I learn an instrument?

In order to make beautiful music on an instrument, we have to learn how to play it. Just like a tree takes time to grow from a seed and eventually bear fruit, it takes time to learn how to play an instrument. It requires regular, careful practice. It can really help if you can have music lessons, either from a qualified teacher or from a good online source.

Which instrument do you like best? Is there one whose voice reminds you of YOU? Which instrument would you like to learn? What do you think it takes to learn an instrument? Do you know anyone who plays an instrument very well? How did they learn to play it? Do you know a music teacher? What does s/he teach?
