There are many public stories of people without a college degree starting their own companies and becoming incredibly successful (Steve Jobs, Bill Gates, Mark Zuckerberg are common examples of people succeeding without degrees).
That said, it's important to note that these examples are exceptions, not the norm. In the vast majority of people's cases, it's incredibly important to get your degree. Here are a few key reasons:
- College exposes you to a variety of people, classes, and ideas
- College degrees show your future employer that you're capable of committing to finishing something that is difficult or challenging
- Degrees will give you the credentials to work in particular fields or diciplines
Most importantly, a college degree will add tremendously to your lifetime earning potential (see below)
