Future jobs?

Hello!
I am here to talk about my possible future jobs. Here you go!

-Footballer
I have been playing and watching football from a young age and I think if practice and be focused enough, I will be able to make my career based around football.

-YouTuber
 I would love to be a YouTuber and not because its sitting on the computer talking to yourself. Mostly. It's because I am already doing YouTube and it feels really good getting all the support I get, and I know its not a well paying job if your not too popular and I know getting popular takes time and may not always happen, and that's why I put my backup: Footballer.

Now for the questions.
If you want to have this job, what kind of subjects should you take at college?
Football: P.E and other physical subjects.
YouTube: Depends on what type of YouTuber you want to be, if you want to be a person who makes stuff, you should take graphic design, and other design subjects.
What other activities could you do outside of school that would help you develop skills for this job? 
Football: Practice and play for your club. Practice makes perfect and playing for your club helps, even if its for your college or just for a club.
YouTube: Don't give up. Even if you have 20 videos and 10 subscribers and two of which are your parents. Don't. Give. Up. Here is a inspirational video you help you.
