High School is incredibly useful. You learn about math, science, English, and all that good jazz. But what things do you REALLY need to know for after you leave home? I personally never even knew what a mortgage was until last year, and I'm almost 21! Learning how to file taxes, budgeting your money, taking out loans, and other life preparation skills are very important to know about BEFORE you leave home. Leaving without this knowledge makes you a deer in the headlights and can leave you extremely stressed out at times. This will be a guide to help you learn about some information that not only college students need, but anybody living on their own.
