Drawing a circle doesn't have to be a perfect since the circle will be erased after all. Just keep drawing though and you're not going nowhere if you keep on drawing.

I guess that is true, but even then I try to draw something and I still can't. I don't know what I am doing is all.

It IS true as circle only serves as a guide and will be erased afterwards. Lemme give you an idea on what to draw... how about drawing your sona based on the events happened to you irl? Maybe like slouching?

Also when you're trying to draw don't just jump to details yet. Make a sketch and messy as possible. When you start lining that's the only time you clean up the mess.

I'm also learning how to draw, my sketches are messy. Besides you may want to watch streams on how the artists do their drawing but do not trace.

I would so do that, though I don't know how to draw the body.

You may want to use this as a guide...

Thanks, but I think I am going to stick with drawing shapes for now. I can't seem to draw them

Just don't get discouraged. Whatever stuff you have on your mind that you wanna draw just draw it. It doesn't matter if it doesn't look good at first since it's a sketch and you'll be correcting them anyway.

it doesn't help that I am on a tablet and it is harder than paper.

Make your sketches first on a paper then.
