You will be surprised how much you know. Comparing with others is almost always a losing game. Trust me because I do this a lot myself. There is always someone whom you want to be like. But remember there are a lot of people who want to be like YOU. So just focus on yourself and keep becoming a better version of you and most importantly, keep an eye on your Goals whatever they may be. Remember that there is a cost to everything. You may look at someone and say "Wow they are so smart or successful or whatever". But do you know what they don't have or what they truly desire ? You will never know. May be what they truly desire, you have it.
