Often when you draw for example a cat you draw it a certain way. The next time you draw a cat you remember what you did before and you repeat it. But there are lots of different ways to draw a cat and I am sure you can come up with more then one way. Mind you there are books written “20 ways to draw…”
One of the days in the sketch book challenge is to draw multiples of one thing. I dare you to have a go and have some fun.
