You have to start somewhere
I have never studied in an art school, and my parents never expected me to be an artist. They do find the art beautiful, but somewhat beautiful and meaningless. I studied physics, maths and whatever else to keep my brain busy, and finally I got the time and opportunity to do whatever I wanted.
So I start. Start visiting life drawing sessions, sketching people on my way to work (the real work!), watching YouTube videos, subscribing for classes, - investing in something that for many people is just a hobby. But isn't it great, to have a hobby? Even if it is "just" a hobby among a couple of other things I enjoy.
You do not have to think that whatever you do will change the world. It is already enough that it changes you.
