People proceed through life at different rates. Some sky rocket to their dreams in a matter of months, some never make it.
By comparing yourself to others, you will be down hearted. Not everybody is in the same boat, and people with the same dreams, will have different circumstances, which alter the speeds they get there.
So I suggest comparing yourself, only with you! You need to look at where you are now, to your past, and where you want to be. Are you progressing at the speed you want? If at all? Set yourself milestones for certain dates/times. And try to push yourself to them. If you are smashing your milestones, make them harder, push yourself.
