You’ve got four kids. When do you start paying for college?
I do circus tricks on the side
When you have kids you just manage. You do whatever it takes.
I'm with @formernuke, we have zero dept except mortgage. The house will be paid off by the time I'm 43-44 in 6-7 years. We make double / triple payments every month.
None of my gear purchases have been impulsive. 90% of my gear was used. I don't pay for fills, I don't pay for nitrox. Hell even the diesel used to run the compressor is reclaimed heating oil from people's houses. I am super cheap. I'll do backflips if I think it'll save me money. I am my own mechanic, my own accountant, my own landscaper, my own pool boy. It's not hard to save when you don't pay anyone else to fix or maintain your stuff.
