Hey Ryan, I believe that life is far too short to not do what makes you happy. Life is far too short even if we live to old age, which many of us may not make it to. It could be me being a soft hands 32 year old, but I believe the present moment is all we truly have.
I think more of it as retrenching, while I'm far from your business size and experience, I took my foot off the gas completely last year. My wife and I were running our business together and only several years in I found myself giving all of me, and unfortunately, most of US to it. Only had 2 employees beyond the 2 of us. Small.
We didn't do anything outside of the biz, all we talked about was the biz, my mind never turned off, even when it should have been.
I've always been the type to try to give my 100% at what I do, which leaves little room for anything else. I realized I did not want to run anything larger, and we decided together that it would be better to not run a growing business together.
So I retrenched, I started focusing more on assessments and consultations, while still taking care of established clients, and their referrals as I wish.
I started climbing for a couple different friends who each have their own biz with different specializations, allowing me to still maintain whatever schedule I wish and not having to deal with any behind the scenes.
The jobs I do for my company I mostly do solo, or will bring someone if need be. Most of what I do now are smaller-medium jobs with referring out bigger ones to said friends. Often times I still get to work the job and help out the client while not having to deal with any bs.
A year later and I'm actually doing better financially, and a complete turn around mentally (not depressed anymore, yay). I found a balance that works for me perfectly, and I have such little resources by comparison.
I know you could retrench to a sweet spot where you still get to do the aspects you love, while successfully avoiding the stress inducing aspects. You have the experience, equipment, and resources to specialize however you want to. You can achieve a balance.
Our society is obsessed with growth, I'd rather be content, and hangout there for the rest of my days. You could stick iflt through for 2 years, but what's 2 more years after that? However, even 2 years is still not guaranteed to you.
