how do stop thinking about.....

something that could be a problem in the future (9/10 months)?

how do i stop so i can give myself the best chance with a girl i like? (i am a male)

right now i wanna focus on pursuing this girl and other things (like getting a job before i graduate). But i cant stop thinking about that potential problem.

thanks.

What exactly do you want to stop thinking about? sorry for asking the obvious
