I have been there. I studied hard, got into best colleges, got decent grades, but when I realized after my Master’s, when I got no job after months of trying, I have been depressed so long that I am still not okay. Even now, I feel like all that education is as pointless. If you can, chase after your dreams, but always be prepared for failure too. But failure should never be the reason to not chase your dreams. Take it from a failure like me.
As an addendum, don’t forget to have fun. Dreams are not end all be all of life. Fun is extremely important. And that fun is in the chase.
