“when i think about myself , my goals , my dreams i end up quitting thinking that there are so many others better than me”

It's totally normal. Everyone has someone who is better than them in something. but you probably know what einstein said, right? "if you judge a fish by its ability to ride a bike, it'll think it sucks all its life". If you compare yourself in fields you're not meant to be in, or which are your weaknesses, of course you'll find better persons. but find your own field, and yes, they will be people who are better, but also people who are worse than you.
