I want to learn how to draw and I'm studying architecture?

use your left hand to draw, practice eye and hand coordination by bouncing a basketball with both hands each till you can do it without stopping. That particular motor skill is undeveloped. when you are drawing, turn the paper upside down and try to draw that way, trust your eye to guide your hand. switch hands and do the same. start with simple shapes first then move on to ellipses and circles and squares. practice ,practice,practice makes perfect.
