how would I learn to draw?

I taught myself how to draw and started at a very young age as being an artist is all I really wanted to do.
To draw first you need to see that everything is made out of lines...I litarly view the world as a series of connecting lines.

My advice for you is to start simple as a child I drew simple things ..as I got older my drawings were more complex.
for my example ill use a butterfly...lets look at other peoples line art of butterflys via google. Get ready to draw exactly what you see...do not trace...draw line for line a simple line art of a butterfly by looking at your screen and then drawing on the paper in front of you....do this a few times with only simple line art.... after some practice move on to a more complex line art of a butterfly and practice drawing it.... then move on to different poses ...its wings folded and different angles....finally move on to a real picture of a butterfly...even practicing with coloring it in.
Soon you wont need to look at a picture anymore and can draw it from memory .
Use this method on other insects, animals, or inanimate objects...even people.
it takes time and practice but you can do it!

If you would like to see some of my art to verify if ill be a reliable source I would be happy to show you some. Otherwise since im on my phone I dont want to bother unless you want me to :P
