I chased my youtube dream because I did not like being forced to work 8 hours continuous in uncomfortable clothing. I did not like not being able to take breaks and I wanted to be able have pets and be home with them. I also wanted to be able to have the freedom to to create what I wanted when I wanted to.
I always suggest having a backup job when starting. Being broke is not fun. But being broke when your young is normal so work your way up into management and then quit your job to follow your dream once you made it into a full time career and I promise you won’t regret your experience you will have gained. I have more life experiences that have taught me hard lessons.
