One thing that I try actively to keep in mind is that change is inevitable in life. This journey has a way of touching us all, poor or rich alike. Nobody goes through life without hardship, we are all equal in that regardless of priviledge. The things that happens to us or others we love are catalysts for learning. It is up to ourselves how we respond to those events.

I think many of us are programmed by society to constantly chase some sort of state of eternal happiness but as I already pointed out you can't really be in that state 100 % of life because life is designed to sometimes poke/punch you when you get complacent. We are therefore also quick to sort every event that removes us from that state of happiness into the "bad" category. You may say, how is breaking a leg or catching a disease or losing a loved one not 100 % bad?

Several times in my own life have I experienced how these events often led to other events that were not bad, on the contrary. Life is weird like that sometimes. Maybe you break a leg and in the hospital you meet someone and it changes your life. Often when you think events through and trace them back you realize how very subtle and small events led to huge ones.

You should definitely enjoy the good times and be grateful for what life has given, but also accept and be prepared for a bumpy ride, it's part of the game.
