Last week I came across this tweet from Craig Clemens. He recently turned 42. To mark the occasion, he put together a Twitter thread of the 42 lessons he has learned on business, relationship and life.

To give you a bit of background, I first came across Craig Clemens when he was interviewed on one of my favourite podcasts (My First Million). He is an American businessman and entrepreneur and a co-founder of Golden Hippo Media.

I find a lot of joy in collecting these type of lists from successful people. They give you a great perspective into how someone thinks and the way they approach their life. You can learn a lot.

I’ve listed his lessons below. You might not agree with them all, but there are some good ones in here:

1. Write letters to your parents sharing your thoughts on your childhood, both angry and happy. Send the happy ones.
2. There is no such thing as being overdressed. There is only making other people feel under-dressed.
3. Don’t manage your own money unless you’ve trained your whole life to do so. Better to focus on making more money, while letting someone who has trained their whole life to do so manage what you make.
4. Some things you will outgrow, and then you will miss them, but that’s ok (and doesn’t mean you should go back).
5. Look for little tweaks that make a big difference. Putting on nerdy blue-light-blocking glasses increases your sleep quality by ~ 15%. That’s an hour a night. Let that shit compound.
6. Put all of your eggs in one basket, then watch that basket very closely (Druckenmiller)
7. A good therapist is the key to a good relationship.
8. You won’t understand dog people until you get a dog. Then you won’t understand how you lived so long without one.
9. Your parents are going to die. To ease regrets, pretend the next six months are their last, and plan accordingly.
10. That text message, email and app notification can all wait.
11. Checking stats or a clock or your portfolio 20 times doesn’t make them move.
12. If you’re having trouble getting started, make a micro commitment. Just five minutes of writing. Or five minutes of exercise. You’ll be surprised how easy it is at two minutes in, to extend the clock.
13. Send a high-quality gift to anyone who spends free time with you on the phone.
14. You can’t order everything on the menu. Ask the waiter for the three best things, and enjoy them greatly. Don’t FOMO about the rest. Do this in life as well.
15. Seek to make great introductions (but never cold). They will come back to you tenfold.
16. The best way to excel in anything is to form a peer group and brainstorm on it with other passionate people regularly.
17. The best time to invest is when you know it’s the winner, but the rest of the world hasn’t quite figured it out yet.
18. The real rate of inflation can be found in rare things people want to buy – real estate, stocks, art.
19. Back up your pictures. All of them.
20. People who use you can still be in your circle, but never forget who is who.
21. You don’t need to wash your face. Seriously. It’s bad for your skin microbiome. Just splash water in the shower.
22. Don’t ever invest in a bar, restaurant, or friend’s passion project, for reasons other than passion.
23. When in doubt, pay for the entire bill.
24. When unsure, tip higher.
25. Tip in advance for better service.
26. You get what you ask for – and often for free. “Is there a volume discount?” “Free upgrade available?” Possible to rush it?” are often answered “Yes”
27. Don’t post a picture in front of a plane unless you flew it yourself.
28. Don’t purchase your primary residence until you are married. Life can change too fast and renting frees up cash to invest.
29. Focusing on improving your sleep is easy and worth it.
30. If bust, meditate once a day. If really busy, meditate 2x a day.
31. After you turn 35 do no attempt physical activity without a stretch or warm-up.
32. When you lay down to sleep, give yourself three praises on what you did well that day and think of
33. three things you are grateful for.
34. Do not gut renovate or build a home from scratch unless you will for certain live there for 10 years.
35. Carry a good set of earplugs and earphones with you at all times.
36. Suntan lotion is the best form of long-term skincare.
37. LASIK surgery (or PRK) is a modern miracle and worth every penny.
38. Ruthlessly discover your addictions and relentlessly break them. But only one at a time.
39. Buy a little bitcoin and give it to your grandkids (but put it in a trust first)
40. If a private investment is easy to get into it’s probably a shit deal.
41. Plan your exit well before you need to.
42. Never trust a man who eats pizza with a fork.
43. Find your oldest email box and sort by reverse order. Read and enjoy how far you’ve come.
