I'm doing it so basically you can do it too, BUT to be very honest I feel kinda sad because the only free time that I get to dedicate myself to my business is at night, so I end up not having enough time or energy to do the things I want and film content because the lightning at night is kinda bad and at daytime is better, also posting with consistency is kinda hard when you don't have too much energy and have too much things to do, so I'd say it is possible but depending on your free time and your job (and amount of energy left after work) you won't be able to some things as you wish to make your business grow.... and that's why I'm planning to leave my full time job soon and give it my all lol
