I’ve felt somewhat similar before, strangely after achieving success that allows lots of free time.
Years ago I left oil&gas during a downturn to sell life insurance. It was supposed to be temporary until oil came around again, but I realized I could do well.
I went from an independent producer working from home before it was cool, winning lots of awards and trips put on by carriers to building a full-service brokerage with offices in multiple cities.
I don’t really have to “work” per se, aside from reviewing productivity with regional managers and helping formulate plans to get or stay on track for goals.
This actually led to boredom as I would consider myself an A type guy and like being busy. I could keep growing, but then I would be super busy to the point I neglect family. Likely for years.
I found an outlet in hobbies. I have a 4 year old in taekwondo and signed up to do it with her. We are in different classes of course but practice at home together. Achieving the next belt or mastering a kick gives a goal to work towards, but it also equates to a bonding moment with my daughter.
I casually played guitar years ago and picked that up again with the intent of actually getting good, and of course there’s lifting.
I’m competing in my first PL tournament in November, I’ve always just lifted for the sake of it but now there’s a specific goal attached.
I tinker on motorcycles and old cars too.
It seems like once you develop a career it’s easy to get in to a cruising mode without any real sense of accomplishment or meaningful passing of time. The French call this blasé.
Give yourself goals that mean something, even if hobbies. If you need more money go get it, but if you’re just staying busy try wrapping hobbies in to other meaningful things in your life to get more color out of them.
