A high school sophomore thinking that it is too late?
If that helps you, I'm 25, married, and a programmer for 12 years already without any art background (I started programming professionally very early). That means my thinking/way of seeing things is all logical, and in if's and then's (the programming way).
I can barely hold a pencil, since in all those years 99% of the time I was involved with a keyboard and I barely needed to handwrite anything.
And I decided to really get involved with art now – started this month. It's being REALLY hard, my hand HURTS when I take a pencil, and I can't even draw a damn wave/connecting lines/anything (see my SB, it is the worst SB around here), but I'm loving it and I know it may take 5 or more years. More than an average person and WAY more if I had pursued that earlier.
But still, I'm not in a hurry and I don't even think it is late.
Do you know when is it late? When you are dead.
