Specifically, I’d recommend living on a small portion of your income and saving a multiple of your living expenses. It’s far more painful to cut expenses back than it is to keep them from growing, and the more years of expenses you have saved the better a position you’ll be in. If you take this approach and there’s no bust, you’re still in a good place: you can retire early or support things you believe in.
