I'm glad you're good at cooking, I believe we can't be a master of everything, we just have to find what we're good at and stick to it, I know someone who is very picky as well, she doesn't eat at people's houses that much. Talking about sketching I'm never good at it I don't think I can ever be good at it though.
Right we cannot do everything but we can do anything we try for. Cooking is my kinda thing.
Sketching is easy you can do it if you want. You just have to put your mind into ease. Then see the magic.
