Some side hustles might require you to invest on equipment or inventory, while others can be started with minimal expenses. You can choose a side hustle that you can start with the initial amount that you’re comfortable with. There are also some side hustles that don't require you to spend money to start. You can gather and utilize all your existing resources like your laptop or software. For some side hustles, you only need your knowledge and expertise. If you think that’s not sufficient, you can find a mentor or search for free online courses covering topics aligned to your side hustle of choice.
