Haha dude too right - I whinged to my boss about my net-free cashflow and how pathetic it was. I then realised how much was childcare/0% cards for refurbishment bills. Once those are cleared I am on a highway to FIRE.This thread actually cheered me up a bit. Because I didn't know how much I'd really need in retirement and hadn't really thought about it before.
Realising that mortgage plus child maintenance was half my current outgoings is good, because it means I should have an ok amount of money in retirement when those things no longer apply. I'll be 70 by the time my mortgage is up though, who knows whether I'll clear it any sooner.
Be ok as long as state pension still around.
