Blogging is a great side hustle because you can do it at your own pace anywhere you want. It's not a quick and easy way to make money, but there are a lot of ways to make money side hustling while blogging. You can sell advertising, become an affiliate for other people's products, sell your own online product, and more. It does take time to build up an audience to be able to make a decent amount of money, but once you have a large following, you could earn over $15,000 per month or more (we do).
Apply for new scholarships and grants. A lot of students think that they are only eligible for funding when they initially apply for admission. This is a mistake! There are often new scholarship opportunities for upperclassmen, though they aren't always widely advertised. You may also be able to apply for external scholarships or grants, which are offered from groups outside of your school.
