the grass is not always greener on the other side. While it may seem attractive to quit your job because of A,B,and C, dont forget what a job is. Its something you show up, do, and get paid for. Maybe a little mundane but other than doing your job, no risk.
A business on the other hand, you can show up, do your best, and fall flat on your face. Business is full of risk as has no guarantees. It depends solely on you. Ive seen idiots succeed and smart business people go bankrupt.
Its also hard to have your foot in both doors. If you dedicated all your time to just one thing, then maybe it would turn out better. Its something that I would reccommend doing because its a great business, but only if you have money saved up in case things dont go as planned. Good luck regardless
