Did you use FireCalc to determine if you can retire?
Yes. Like W2R, I have run Firecalc and every other retirement calculator I can find. I have also beaten my spreadsheets to death. Firecalc has me at 100% even with a higher increased spending than I am planning.
Seeing all these great replies really affirms that it is time. I will never be as healthy and active as I am now and it's time to live my life for me. I think I just might submit my resignation this week. If it goes south I can reduce spending and/or get another job (although not for what I am making now). Plus, my wife still has her income.
Thank you all again. You have validated my thoughts and given me the nudge I needed!
