How hard drawing can be?

I believe drawing is as hard as you make it. There is a difference between putting a lot of effort into your art work and actually working hard on it. For me if I have to work at a drawing it usually is not going to come out well. But I sometimes spend hours or days on a drawing and never have to work that hard at it. When it comes to drawing I really end up drawing more then one thing because once I have different ideas I hurry up and just draw because I do end up forgetting.
