Allow me to tell you what I would consider doing if I were, as you are, pretty much set financially. Maybe this will be of use to you.
- buy and renovate a house in my town for my mother to live in as often as she is able to (she lives far away, with a separate family)
- take my mother to the country her family emigrated from, for a nice long trip
- spend a year in the country my wife is from, getting to know her extended family far better than I do
- run for local office in my rural community in order to fight for safer bike and pedestrian access to roadways
- spend a year or so studying to homeschool my daughter (if you want to learn something, try to teach it)
- get involved with a really cool local youth outdoor adventure group, perhaps even find a way to get hired (insurance!)
- identify the most effective means to tackle voter suppression tactics and fund it and otherwise help implement it
- build a wooden boat
- take my hobby fermentation hobby to a retail level, if not a distribution level
- go deep, in one way or another, on any one of the open source projects I am super interested in
- learn to play one of the instruments I put down as a kid (long list!)
- build or/and run a parenting community site that doesn't exist where I live
The grass is always greener, but boy would I love the ability to drop my busywork that pays the mortgage and do some of the above. Maybe, if you imagine yourself in my shoes, you can come up with some ideas that get you excited.
> I feel like I've hit my zenith already
I peaked in high school, and I realized that long ago. The company of a group that cares if you are on your way up is probably not going to give you much solace.
