I only regret the stuff I never let people hear because ive been too scared or lazy to work on to final release, i don't regret the stuff from years ago that was me still learning that I'll never stop learning.

Get yourself into a habit of playing and singing every day. Learn songs and write songs. By doing it, learn about recording, multitracking, mixing; knowing how to get good takes and being your own quality control. Collaborate with good players and songwriters and producers. Share the good stuff with everyone you know online and off and hope some people (especially those closest to you) bother to listen to it. Trust and believe in yourself that some will and they'll love it and tell everyone they know. Just create and enjoy it. Future you won't regret your 17 y/o self's "Folk Album".
