Like they say, hind sight is 20/20. Those hard experiences of break ups in the long term were a good thing. Been there and done that

Yes, I have no regret, sometimes I believe these experiences, despite how painful are what teaches us the knowledge we need to know. People don't truly learn unless they've gone through the experiences.

As you become older, although not always the wiser, you tend to have friends with similar interests

True. As for me, I have become more knowledgeable, though not wiser and I noticed that some sort of compartmentalization has happened to me. I no longer have that much interest or people, except for a few people that we share interests and nothing more.

In the aspect of money, I think it's just how we're encoded, although it's not such a great thing, but people just tend to want to move with others they consider their class or people in the same bracket with them in all aspects of life.

As for being older as well, physical limitations really suck.

It does, sometimes I miss when I was younger, but I despised how foolish I was despite being full of energy and endless mobility.
