I'm nearly at my 30s now, I have been living a, somewhat mediocre life, born in a developing country, grew up in an average family, neither poor nor rich, received some proper education. Although I do feel blessed compared to a lot of other people, being healthy, having an ok-looking appearance, with a decently paid job and all, but at times, I still feel unconfident, question my own abilities for not being able to do greater deeds, wish that I was born in a developed country and grew up in a better environment to be more intelligent, to become a better version of my current self, and stay on top of the society.

Anyone has had the same feeling? Anyone has managed to overcome this and enjoy a life that was designated when you were born?
