"I have certain players who I look up to massively, but you have to remember there are so many variables that judging yourself against other people is quite dangerous. The only person I should judge myself against is myself.

Please clarify your specific problem or add additional details to highlight exactly what you need. As it's currently written, it’s hard to tell exactly what you're asking. See the How to Ask page for help clarifying this question. If this question can be reworded to fit the rules in the help center, please edit the question.
To look up to someone means to admire and to respect them as a human being, for what they have done or for what they stand for.
Here, the person means that she has players she admires, but that you still have to keep in mind there are too many criterias to judge a man. For example, even if Bruno Mars might be a better singer than you, you can't straight-up feel bad for it as you surely have qualities he doesn't have.
The last sentence is open to interpretation, but I would understand that as "be your own best without minding too much about the others", through introspection and finding who you really are based on who you were, and who you aspire to be.
