I'm all set myself. My only expenses are taxes and mortgage. I grow my own food in the backyard for fun and I'm pretty sure I can scale it up when the going gets tough.

Personally, I believe that giving should be done without expecting anything in return, otherwise it becomes an exchange, which I find incredibly exhausting.

You’re not “all set yourself” if you have little in the way of savings and are resorting to derivatives trading to make your mortgage payments.

Defer your donations until you have a year of payments in a rainy day account. You can’t donate if you’re homeless.

I'm sure it's a troll. It's a humblebrag at best, troll at worst.

But its not a troll. My donations are no different from a startup founder going all in. Except my vision doesn't end up with me making billions of dollars. I'm working towards a vision where people around me has food to eat, gets education, and has a comfortable shelter.

So retirement? What happens when you need care?

Do you wanna / have to work forever?

I think that this is a personal choice, not an objective "it is wise" choice.
