Comparing yourself to someone else is a complete waste of time. You can never be that person with the exact environment they grew up in, let alone your genetic makeup.
You do you, Set your own goals, and work to make today your best day.
As someone who also went through this transition in my early 30’s ... yeah I’m more chill and pleasant to be around but god damn it I get so much less done
I get more done. Before it was "why bother trying, I'll never match them". Now I just put in consistent effort - small amounts at a time - rather than giving up before I start. Guess it depends upon your underlying personality.
