Wear sunscreen. Seriously. Every single day. 365. Rain or shine. Sounds like a joke, but just wear sunscreen. In 20-30 years you won’t regret it.

Regularly invest into a broad market index fund. At your age a few bucks a month will compound and you’ll be a millionaire before you know it. It gets a lot harder the longer you wait, so just do it.

One thing that has gotten weirdly apparent to me as I’ve gotten older is that I’ve always taken care of myself, most people my age have not and it’s apparent. I have no real aches and pains or physical ailments, when most people my age have a laundry list of them. People always peg me for 10-15 years younger than I am. Exercise, eat well, drink water, avoid baking in the sun, avoid drugs and drinking in excess, learn to meditate, (wear sunscreen). It sounds like a lot, but I promise you won’t regret it.
