It's cool how Dose of Fousey put it out in the world that he wanted to do a collab with Kevin Hart and it happened. I believe that's how life works if you continuously work towards you're goals and put in the work. If he did not build himself to the level he is on youtube of consistently creating videos, posting them, getting millions of subscribers and working it would have never happened.
Put things out to the world, stay focused, work hard and live the life of your dreams.
It's possible, you just have to work hard and believe. Congrats, bruhbruh.
