Read lots of post talking about how comparing yourself to other people is bad and not right thing to do. I think that actually it is not so bad. If you think that someone is better at something - don't get discouraged! If you think that you are ahead - don't put yourself up too much... Yes, be yourself and strive for better! Competition is a way for a progress!
