Final remark on the subject from a person who loves art, and hangs out here to enjoy it, but is herself totally incapable of producing art. From my point of view it looks as if all of you are manifesting a superpower! Haiz, Martti, Frenci, Sc0ut, Unlos, all the rest of you: thank you, and please keep doing what you do. It is valued and appreciated.
I figured out that, for me, there was absolutely no point in beating myself up because I'm the only person in my highly artistic family who lacks the ability to paint or draw. Instead I concentrate on the stuff I can do: the three-dimensional things. I write, carve, work wood and leather, cook, sing and make gardens just fine. So that's what I do. That and visit here to enjoy the work of the people who can make art.
So I say: do what you are able to do, enjoy doing it, keep learning and trying. If something you have made disappoints you, well, no making is perfect - try again and delight in the process.
