Thank you for a concrete example. I think you will agree though, that the outcome you describe isn't inevitable or most-likely.

Over time you will likely figure out a good life-work-philanthropy balance. Much of the conversation within EA is about self-care and long-term planning. If giving 70% of your income to charity works for you, that's magnificent. But if you realize you need to give less and take more care of yourself so you don't burn out, that's the appropriate decision.

I gave 50% one year but it didn't work out long term. I've been giving 10% for almost a decade and intend to ramp up to 20% in the future. My wife does 10% too - it works out well for us.
