The best piece of advice is around time. Time is a constant. You can't mess around with time. Leave it to Elon Musk and Bezos to mess with space. But still, no one can mess with time. With time it's either for you or against you. When you first start, it's really important that you don't want time to be against you. The thought is as a side hustle, nights and weekends you have a salary, you have your health insurance taken care of. But, as soon as you leave your job to focus on this hustle and the hustle is not to the point that it's paying your salary or paying for what you need then, time becomes against you. Be smart about when you make that decision to go full time with a project and how you want to approach it.
