This is another reason I'm on the fence. Don't hate the work, have a good boss, bunch of flexability, some really good co-workers.
I miss some of the people I worked with or saw daily, some life long friends
I worked in over 125 Automotive dealerships
under contract, sort of in house Contractor/Facility Management co./Construction,
for a large dealership group/s in multiple states...
I was my own boss, since 1985...
I also owned a Golf Pro-shop retail sales, custom fitting, repairs & lessons,
started that in 1997 when I moved farther east, to Rancho Murieta CC, until 2007...
When I semi-retired, I started the pro-shop, kids have a place to work
learn how to deal with people...
(Semi-Retired a misnomer, I worked far more hrs than I ever did, in the day to day stuff)
I also still did consulting for about 20 year, on a fixed salary + expenses
but on my schedule, my time line, 40 hrs a month, mostly after hrs
but I usually did far more than that # hrs usually...
Paid very well for my time too, I set the price & when...
I knew all the owners & their families, for 25-35+ years...
I had honey do list for months every year, from their wives alone
IF, I wanted to still work...
I miss the racing most,
I could afford to do it right then
I don't miss the being on the road constantly, for work &/or racing
I hated that part... I still do...
I rarely even leave the county now...
Seemed like, more successful I got, the more I lived out of a suitcase sometimes
always in an airport going somewhere, or on the road staring at a windshield
for a race or for work...
I put 350k+ on both my last 2 work trucks Power Ram 4x4 2500 5.9 12 valve Turbo Cummins,
you can say I had some seat time...
I was sick of not seeing the kids, or their sports, or games or my dogs (especially),
or my cars or the pool...
It's hard to give up a great income & live off your "nest egg & S/S"
or for me more the investments I made, when I was doing well,
I own everything I have no paymenst or mortgages, all mine...
Makes it a bit easier, why I did it in the 1st place, so I can relax when I'm old...
But, it gets/getting easier every year for me so far...
I'm not rich by any means, but "I can budget like nobodies business/I'm frugal as F---"
You'd be surprised at what you don't really need or can live without...
you'll learn
I have so much time, I now procrastinate most everything...

It's the mantra,
it can be done tomorrow, no hurry...
When I 1st fully retired at 62 or even semi-retired at 38 (1997),
only did consulting & running my Pro-shop, kids worked for me etc.
Everything was still
gotta' get er' dun, times a wasting, time...
Now, I learned to pace myself enjoy stuff, "work" it's not that important...
Work is only part of your life... don't waste it all working
At 66 now I got it down pretty well...
If you can afford to retire
& can live with yourself, I highly recommend doing it...
It is a bit tough at 1st, takes a while to wind down & get in the retirement grove
not punching a clock, checking in or deadlines, that have to be met...
You will be shocked,
how much you don't spend (for work),
as much as how much you will spend too (just living)...
Those doing it,
Good Luck,
it's a lil' different for everyone, make it your bitch, don't be it's bitch...
