write a song and sing it in public

No, I do not plan on becoming a GOOD or SUCCESSFUL singer-songwriter, but just to do it. I can make the worst song in the history of mankind, but it's still a song, and I can sing it like a crow, but I have still sang it. :-D The quality of the video doesn't need to be any good, and it's ok no-one ever watches it, or watches it just to leave a mean comment. This is part of teaching myself "done  is better than perfect". I don't need to MASTER this to be able to DO it. I just have to DO IT.
