You should focus on building a business or developing a product that would make you money for a long time. When you think about how to make money, hit and run hustles will seem appealing to you and when you burn through that you will have to go out looking for new hustles. Always focus on building a business. If you're low on capital you should start with dropshipping, grow into fba with your own inventory and then maybe build your own ecom site. If you're 0 on capital, you're probably better off getting a job for now until you save up enough.
