I learned most of your list in my teens and twenties, probably saving me years of struggle. In my 50s, I’m working on:

1. Culture 100% belongs to people in their 20s. Culture changes faster now than anyone can keep up with, even the young. So why try?

2. Your government does not care one bit about you, even at the local level. The social compact died in the 80s in the U.S., and that makes getting older pretty hard.

3. Ageism is a thing, and you will be taken less seriously just for looking older, even if you have decades of experience in an area. Young people today don’t want to work with older people at all, and sometimes will openly wish you and your generation were dead, at 50. Ignore them. Start another business.

4. The mainstream medical establishment doesn’t know shit about how to be truly healthy, and even less about women’s health. This is not like to change as allopathic medicine is mostly about triage and pharmaceuticals. Find a good holistic doctor or naturopath who isn’t a quack peddling supplements.

5. Your kids have to learn everything the hard way, through their own lived mistakes and trials, just like I did. Watching them flail can be hard, but necessary.

6. You are only as good as the memories and legacy you leave behind for others. Otherwise everyone will be utterly forgotten in one generation or less.
