Contentment is fleeting and evolutionary.

Major milestones for me were:

16 got laid. mind blown. reality attained when she moved on.
18 and traveling to Europe with a backpack and Eurorail pass. I came home with a very different take on nearly everything.
21 I could order a drink in a bar/restaurant or buy freely from a store. something that I worked hard to side step the previous 4 years.
30 met my future wife, married at 32 - overcome with the stress of being ultimately responsible for someone else.
33 my son arrived - overcome with stress of failing him.
34 my daughter arrived - overcome with joyfull emotion.
36 absolutely killing it at work, top of the game.
50 neglected to maintain the skills that used to succeed at work

55 working on a path to get back to contentment. still have my wife, kids, and respect

I have no advice.
