Sure we could say he will die one day, maybe tomorrow, so just blow it
No, there's a happy medium and personally I think 25% is pushing it.
If saving a fuckton makes you feel great then yeah. But skipping kid free vacations or not taking memaw to dinner because you're strapped because you want to pull out more than your salary in 40 years you need to consider more than accumulation.
If you save that much itd probably work out better to pay tax now and if you're not getting a match how much is it benefiting you to have it in 401k?
