Sex: There's no single way to do it "right" but there are lots of ways to do it wrong. Not being respectful and tender towards your partner is usually at the root of "wrong" ways to do it. Also, there is no rush. You may think all your friends are "doing it." They're not. Take your time.
Some books you loved when you were a toddler: Alexander and the Terrible, Horrible, No Good, Very Bad Day, Horton Hatches an Egg, Room on the Broom, Gruffalo.
Stage one relationship: first few dates. Stage two, you really like them. Stage three, you love them and are exclusive. Stage four: you commit to building a future together. You’re going to have many stage one and two relationships. Probably a few stage three, and if you’re lucky you’ll have one or two stage fours.
Crushes are fine but I beg you not to waste your time and energy obsessing about someone. Really it’s just a way to hide, to feel something without risking anything. F that. Turn your attention to something creative, constructive or productive. Make art, train for a race, volunteer or get a second job. Discover WHAT you love. Pursue that and your people will be there.
On a job interview, mention a high-level educational goal such as MBA or law school. Their estimation of you will go up without them even realizing it. Your offer will be higher. Also follow, up with a brief but we’ll-written (professional) thank you note/email whatever.
One regret I have is how sure I was that I was in the right. Looking back I can see now that there were plenty of times when I was the a-hole. I wish I had been able to be circumspect.
Misquoting someone here: “It’s not about getting everything you want, it’s about giving everything you have.” Stuff will never satisfy. Pouring yourself into something heart and soul will.
