make yourself a white paper box

draw it 10 different positions each time do 3 drawings one just contour line, then dots, then hatch
draw it a hundred different times (or more until it looks "perfect" under different light and in different positions with a pencil in realism style
then draw it 20 times more
then draw it another 10 times with different medium for each time

then make a paper cone and maybe find a plain ball
repeat same as with the box

then wait a week

then draw all three objects together without looking at them 5 times

then stab your eye from misery
