BBA Student Here ....Need Guidance on Which Skills to Focus On..

I'm a first-year BBA student. My first end-sem just finished, and I have around 20–25 free days. I'm stuck away from home due to some scholarship issuee (which is already stressing me out), but I still don’t want to waste this time.

Any seniors here who can guide me on which skills I should focus on building during these days...skills that will help me in the long run or be useful in the upcoming semesters?
