It sounds like you are all sorted. I think my attitude on life changed in my early twenties when I first went to work in jungle in West Africa. Villages that had nothing. Kids that either helped dad hunt or helped mum with chores. Their daily goal was to get food to eat and water to drink that day. Real poverty I never experienced. No fancy trainers, no weekends to look forward to etc.
That coupled with my arthritis made me treat everyday like a weekend and possibly my last day.
I don't regret and I don't do what ifs. I would be seriously depressed if I started doing that.

Money, that is an interesting one. I don't do what I did,and find that the more money you it just means that you have more expensive hotels to stay in, or better restaurants. We do the same things but to our new budget, but as long as you have fun who gives a fluff.

I love how methodical you are and know you will be sorted in whatever you do. Interesting about uni etc ... During Covid I learnt python coding from the Open University.

And I need to stop rambling!
