I'm just going to come right out and say it: college (or university) and school is not for everyone. Personally I left school a year early and was only at university for a year before I realised it wasn't what I wanted to do. Despite this, I'm now in a job that I love which stems from my passion for writing; there's nothing I would rather be doing than writing. What I'm saying is that you don't have to go to college to be happy or to have a successful career. Similarly, if you want to go to college eventually, but not as of right now, that's absolutely fine as well.
Despite what many people think and may tell you, there are several careers that don't require a full degree so it's important to make the right decision about your next step without feeling any kind of pressure to go to college.
There's also plenty of different things you can work towards or choose to focus on as alternatives to college. Here are a few examples, courtesy of Livecareer.com:
1. Learn a Trade
Apprenticeships, at one time, were the only way for young people to get a foot in the door to their careers. If you have an interest in a particular trade, such as technology or construction, seek out jobs in the trade that will not only give you valuable experience but guide you toward advancement by helping you with the certifications or licenses you need to succeed. For example, one high-school graduate worked for a pool construction company for several years, learning every aspect of the business before earning her swimming pool contractors license and starting her own business. Another tool to learning a trade is to obtain your certification in that field.
