Would you share yours? I'd really like to hear from an older person. I'd imagine you know 10x of what I do now. It would be incredibly helpful if you could share some of what you've experienced and learned.
I got to kick back a bit and the job was more about delivering accurately and not delivering volume. I spent the first 3 years in that position recovering from prior burnout while still working. I got bored, so I quit and started a business. I worked myself for years right into the ground, burned out again. I took a few months off and relaxed. I ended up geting bored again before I fully recovered and went back to work.
I changed career tracks and switched technologies figuring this would give me a challenge and excitement. A new profession, systems, and rules of engagement. I was truly excited at first and I worked hard. Then I burned out again, before having recovered from prior burnout. This time it isn't due to lack of work/life balance, its due to lack of technological and social satisfaction.
At first I thought it was a bout of imposter syndrome as it's a new career but as time went on I realized it's more about the industry, the direction it's going, and the effects of people getting into STEM for money and not because they're technologists. It's a lot of younger folks who boast about their adderall abuse, get excited to give presentations, and other stuff that I'm really not interested in.
I'm stuck in burnout #3 now. It’s easier to burn out after the first one. I don't have the ability to make a risky move at the moment, I have people who depend on me. I don't know what my next move is now but as you age and your responsibility grows your options shrink. I think I might ride out the virus and look for a new job in the hopes a new environment will give me a push to keep going.
This is common but not a universal experience. I do have much more responsibility now, but also a lot more options; unlike in our youth, we have no unsecured debt, don't live paycheck to paycheck, and have savings, which gives me the ability to plan ahead.
My two cents: I find joy doing challenging work on products that are useful to a bunch of people without needing to be "the next big thing". But what I find more joy in is my life outside of work, in spending time with and taking care of my extended family (including my close friends). The most success I've had with this so far has been at a big tech company. This is for a number of reasons: the product I work on is more likely to be useful to lots of people that way (because a lot of the marketing work has been done already), which also makes the work challenging (because scale brings challenges), and compensation and work-life balance are good so I can spend a lot of low-stress time focusing on family. I personally find the most joy working on things that mostly make money through charging people money for services because it feels like the most honest way for my salary to be paid, but I'm not sure how much that relates to this, it might just be a personal preference. Reading your post, I wondered whether you misinterpreted your big-tech coworkers. They might not have been checked out, they might have just been doing their work while having other interests that were more important to them. That is my interpretation of the people I work with (and of myself). I think it can look pretty lame to excited young people, but it's actually the opposite; what's lame is being super into working rather than other better things.
But as a follow-on, something I've been thinking about recently is whether I can take the useful skills I've built through a career in tech and apply them elsewhere, supported by the savings I've been able to build up. I'm not sure what that looks like, but being able to gather, process, analyze, and operationalize data seems important for lots of things, and that's something I know how to do (and I'm not alone here, software is largely about processing data). But I don't know what the most useful thing is to do with those skills; right now what seems important and in demand is epidemiology, but it's probably too late to become useful to this moment. Probably something in the broad sustainability space is more forward-looking. I'm still looking around.
I guess the two points I'm trying to make are: 1. You may be able to find joy by having more modest expectations, and 2. There may be other useful things to do with the skills you built, you should keep your eyes open for them.
Hope this helps a bit, cheers!
