“Also, when you’re in your mid-20s you’re more polite and effusive. When you’re in your late 30s . . . the nonsense leash you tolerate from monkeys is a great deal shorter. Not after that much life experience. No one tells you what to do. No. “
Pretty much agree. But I still try to be polite.
I think that main reason for the change is that we 1) get more comfortable with ourselves 2) have a better sense of what we want and don’t want 3) and have a clearer understanding of our (realistic) goals in life and what it takes to achieve them.
