Drawing is the start of everything, It's the most fundamental part of the process. Get some lines on a page, pencil on paper. Anyone can do it. 'Mistakes' happen. Accept them.
It is what you are given.
You are trying to communicate the idea of a thing by making marks on a page, a view of reality in a flat space.
As you move into the world of objects, the decisions become much more complicated.
Move around, zoom in, back away, squint. Tilt your head. Consider.
