Ah okay.
In that case I would recommend the most obvious field :

This should counteract the effect you mentioned, the fears of comparing yourself to others, wondering if they’re farther than you. Productivity is inbuilt.
Another thing though… Are you absolutely sure this is your personal dream to attend this exact university?
What I mean is, what can happen is that we cannot recognize if a goal is truly a goal inspired by ourselves or by someone else (parents, friends, society).
You know, those kinds of goals, while they seem to be good and make sense, there is a possibility that if you are honest with yourself, you don’t truly want to pursue this.
I say this not to discourage you but simply to look within and ensure that this is your own goal.
