Short answer - work for a small startup where you wear many hats. Scale, sell or fail - rinse and repeat.
Started as a mechanic, went back to get an engineering degree which got me into a auto manufacture. I found engineering cool but moved to slow and salary growth was very slow. During dot com days things were booming and I had an opportunity to jump to a marketing startup which helped me break out of my engineering shell(such a different world).
I found operations was a very good fit for me - complex machine you have to engineer to work efficiently as the world is on fire. I happen to make a career out of it working with several startups in numerous industries. My job was always started with - fixing stuff young startups get wrong to help them keep up with growth. Basically put business processes in place and be an interpreter between technical and business people so they stop making stupid technical decision that cause long term problems.
It was a great ride and learned a ton about business that you will rarely learn at a big company. I was responsible for various aspects of technical and non technical operations so always had a seat at the table.

My current rabbit hole is tuning my home's boiler to be more efficient in its use of gas. It is an interesting engineering problem because the lack of feedback loop since the thermostat is dumb and specific home variables makes smart thermostats useless as well as boiler sizing more complex than most installers understand. My goal is to add some features specific to my home to reduce gas consumption based on more variables - outside temp, minimum outside temp, sun/clouds and home variables like brick wall temp, fireplace heat, boiler controller settings as well as the wifes 'I'm cold' variable.
I am using a microcontroller and custom current switch as well as IOTSTACK to send inlet/outlet temp and gas valve & circulator state (on/off) to influxdb/grafana so I can see what is happening between thermostat and boiler controller. I have identified a few freebies in terms of consumption and inefficiencies. I have added a relay to delay the gas valve once the boiler starts cycling to reduce "short cycling" which is a waste of gas on startup and a mini explosion every time gas lights. I have managed to reduce cycles in half which helps with wear and tear as well as the number of boom sounds coming from my boiler room :)
I would love to go down the simulink rabbit hole but I think I will not.

I saw my grandparents go through 10 years of doing all the retirement things(beach, hobbies, social hour etc) to keep them more than busy. Then they kind of did it all and just started having social hour earlier and earlier every year into their 80s. Cocktail our started about 11:30 am in the end.
I'm starting my retirement and have so many interest/subjects I want to learn so feel like I can stay pretty entertained for more than 10 years but maybe not.
