I want to add something that's very important. Save, like you were hiding money, any little certificate of completion for classes or seminars that give them out & that you attend. Some qualify for college credit or points towards them.

I didn't know anything about college, & over the years I pitched away an Associates Degree. A credit here, a half a credit there add up. My many certificates of completion were just stuck in a drawer someplace soon lost.
Most know this advice, I was just ignorant or DGAF at the time.
