Do you guys also face existential crisis and how can we really know where we want to spend our rest of life?
For example – the vast majority of tech jobs require one to sit at a desk in an office. There are ways around it, including remote jobs, standing desks, and walk pads, but basically if you're a tech worker, you're in a room staring at a screen for 6+ hours a day.
So, from this perspective, I would suggest thinking about what kind of day makes you happy and fulfilled. Is it one that involves talking to a lot of people? Walking around an urban area? Being alone in the forest? Put the intellectual content of what you're doing aside.
Personally, as much as I love tech stuff, I have grown to really dislike the default work environment. Being a bike messenger or a sailor, while having nearly zero relation to technology, seem like much more enjoyable professions on a day-to-day basis. This has led me to experimenting with various work "formats" that combine physical activity with computer work, ranging from take my laptop to a cafe to use a standing desk and exercise bicycle.
I thought I would love to be a programmer. I didn't start programming until I was 28. I loved programming. I loved building things and solving tough problems that saved me time or automated real world problems away.
It turns out I still love programming nearly 2 decades later, but not for work. I grew to loathe it. I had a deep passion for programming, but most of my peers did not. Most of my peers never really seemed to learn to program and so when presented with a tough problem all they knew was to find some tool or framework to do it for them.
So, moral of the story is dig deeper. Thinking about programming was not deep enough. I wanted to build things, so I should have started from that and looked for jobs where I would be building things, and programming in the corporate world typically is not that.
Work is what you do to pay the bills for your real life.
I'm 39 and in the same boat, going back to school to explore other options while working IT part time. I don't know if I've changed or the industry has or both, but it deels more wrong now than ever. Time to move on!
I feel the reasoning of your question but it sounds like the wrong question.
What don't you want to be doing tomorrow? Next week? Next year?
(but note this is easier for a theory person than a systems person, easier for academics than for practitioners, and easier for those who already have a unique skill set than for those who are still in the process of acquiring one)
Yes, how can we indeed?
I mean, can we even know? It sounds almost like knowing the future. Because in a sense it is. Your life will change. It will change in ways you do not know yet. You will change it. Trying to figure out the rest of your life now sounds tempting, but it's mostly useless. Perhaps not completely, but mostly. Sometimes, you can figure out some stuff in advance, but I don't believe you can do so generally. You don't know the future.
But, on the other hand, do you need to? Because you can be impactful in various ways and many of them -most?- don't require figuring everything out now. Just try things and see how they go for you.
What I can tell you is that if you're really burnt out, then you should probably do something about that part. Should that mean "leaving everything"? Maybe. But more probably it can mean leaving some things and keeping some others. Maybe just changing employer, or maybe a different job in the same industry, or perhaps, yes, changing to a different industry. Or maybe make changes in the parts of your life outside work. I can't tell you what to do, obviously. But do consider all the options, not just the extremes of going on till you burn completely or leaving absolutely everything. I've seen that in many cases only seeing the extremes tends to block the person from making any change at all.
In any case, again, I can't tell you what to do. I'm just a stranger on the internet.
But I did figure out that there are two types of people. One figured out what they wanted to do in early life and went ahead to leave their names in history. The other didn't and perhaps never did.
There is not much one can do. If you are in the first camp you simply could not suppress the eagerness of going ahead and dive into what your destiny is, and if you are in the second then you simply could not figure out.
Just move on and figure out on the road. It's fine if you never figure that out. Most people thought they figure that out but they did not.
