Welcome to the first in a regular series of life skills posts on the basic information you'll need throughout life that isn't taught in school. We'll cover the basics of how to feed yourself, do your laundry, be a good roommate, transportation issues, and personal finance.
Codecademy has a nice overview of what they call 'non-technical life skills' in a brief, free lesson that covers making a budget, saving for retirement, picking health insurance, interest rates and compounding, and more. You'll have to create an account, but you can access this lesson with the free basic account.
