Apologies in advance - this is going to sound harsh, and me brand new on the forum - but be asuured it's meant in the most helpful context.....
1. An education lasts a lifetime. Once you've got the paper, you've got it for life. It's always worth completing.
2. Throw away x-years of time and monetary investment just a few months away from completion for something like Youtube? Verges on insane.
3. Youtube will still be there in a few months once the education is completed.
4. Imagine if one day - perhaps not too far away! - you have to explain to a recruiter in a job interview that you're looking for a job, but no you don't have that college diploma because you dropped out just a few months before completion to chase after Youtube stardom - hopefully they're polite enough to not be laughing as they show you the door.
