A side hustle is a way for you to make some extra cash while keeping your day job, whether that is an actual job or being a full time student. A side hustle can come in many forms. It could be an actual part-time job like driving for Uber. It could be a hobby or something you are passionate about that makes no money at all but increases your marketable skills. Then there is my personal favorite, coming up with a business that you can run in your free time after work and on the weekends.
From reading online, some people believe that starting a business requires spending lots of money, investing a lot of time, and hiring lots of people. The reality is for a side hustle all you need is an idea, some free time, and you can invest as much or as little money as you want into the idea.
