Individuals don't win. Teams do.
This is a saying most of the times used by managers of teams.
And, it is true. Because no man is an island, and you are always surrounded by people. In your private situation, work, sports, school, university. In life.
So, if you want to win, and not only in the meaning of competition or sports, but make "profit" in your life about the things which move you, see if you can form a team. A team which is committed to make it happen. A team with members who want to make it happen, for themselves, and for the other.
Or, as Al Pacino says it in Any Given Sunday" Either we heal, as a team, or we will crumble as individuals. The one who is willing to make that extra inch, to make that extra effort for his team-mate, that team will win".
Do you have the feeling that you belong to a team like that?
