I have compared myself to others in the past - in fairness i know no one who hasn't. I think we're conditioned to feel we have to do so much, be so much - in reality though its a pretty futile exercise, none of us knows what goes on behind closed doors and we need to focus on whats excellent for us, measuring yourself by someone elses standards is pretty pointless. There will always be those more capable and those who are less so but the way i see it - i know most of my friends haven't been through what ive had to go through the last six years so if im not as successful as them its for a good reason and frankly im amazed im still here at all. Hope you find peace with this situation. All the best.
