Not selling the business after being assured it was a done deal was very hard on me mentally. I don't know what has changed since then but I have reached a state where I don't stress too much about it now. Still making great money but just don't give a shit anymore. When shit gets broke I tell the Mrs. to call a repair man and pay to fix it instead of fuming over it for weeks.
I'd call that serious personal growth.
And aint it funny how 'The Universe' works- the biz sale snafu made you feel like things were fooked, and yet now it sounds like you're at a different, higher level as a result. Soon to be followed by yet more hurdles and more levels.
