An issue I always have with early retirement is whether it is morally acceptable. When retiring early from a skilled profession you are depriving society of a big contribution you could have given, that was also expected and invested in by society. Utilising a power dynamic by having more money and knowledge to capitalise on other people exacerbates this issue.
How are you dealing with this? Are you of the mindset that you do not owe anything to society? That it is completely fair, as you earned that money and there is a perfect market that trades all aspects in a meritocratic fashion (e.g., delayed consumption should be gratified this hard)? Or that you were not just lucky to have the talents to earn so much money?
Retirement does not mean you cease to contribute to society. It may allow you to develop new hobbies and passions, build or enhance relationships with family and friends, or give time to your community
Downtime may allow you to think deeply on what kind of world you want to live in, or travel may broaden your horizons and make you aware of issues you would like to address - you could become politically active, or contribute your efforts to a charity
You don’t have to do any of these things, but don’t write off retirement as an empty non-productive life stage. If it doesn’t bring you joy, you can always go back to work ;)
