I remember there was an episode of Who's The Boss where Tony was telling Billy (that little boy with the weird voice who lived there for a while) to put his scarf in his jacket sleeve so he doesn't lose it when he takes them off. 15 years later, I've started wearing a scarf, and I do that every time I take it off. It actually is a pretty good tip.
Similarly, when I got my first full time job, I started depositing 10% of my paychecks into a savings account, like Ross and Monica's Dad had told them on Friends. I don't do that anymore because I'm poor, but at the time, and had saved like $1500.
Also, when I was about 10, I remember learning about the Hypotenuse of a right triangle from a McDonalds commercial. Since then my math knowledge is obviously far beyond that, but at the time it really impressed my teacher.
So what things have you learned?
