what is important is not that you make mistakes, we all do that, but how you deal with them

Yes, quite. But not to say that they don't matter cos it's "only f*lk.

Stop misrepresenting me. I suggest you do as you ask others to do and read my post carefully.

It's disrespectful to your audience and to the music to bash out any old shit.
If you want to play or sing out don't do it till you can.

How do you know how well or otherwise I can play or sing?
