Wear sunscreen
I know; these are not the words of Vonnegut, but stem from a column by Mary Schmich – here is the backstory.
Regardless, these apply today even more than ever. So, briefly, here is an excerpt, taken from here:
Don’t be reckless with other people’s hearts. Don’t put up with people who are reckless with yours.
…
Keep your old love letters. Throw away your old bank statements.
…
Maybe you’ll marry, maybe you won’t. Maybe you’ll have children, maybe you won’t. Maybe you’ll divorce at 40, maybe you’ll dance the funky chicken on your 75th wedding anniversary. Whatever you do, don’t congratulate yourself too much, or berate yourself either. Your choices are half chance. So are everybody else’s.
…
Dance, even if you have nowhere to do it but your living room.
I am going to dance with you.

I love these lines because they are so true.
