This is about programming specifically, but I guess you can experience similar things with many other activities as well. So if you can even remotely relate your thoughts are very welcome.
Alright so, every time when I sit down to programme it tends to start out great, I feel relaxed and kind of looking forward to it. However, at some point there is going to be a bug in the code or some library does not work as I expect it to. I then start googling; try something out; doesn't work; google some more; try more stuff; still doesn't work. While this is of course just what coding is like, during these "google, test, repeat" sessions I tend to go faster with every iteration and at some point I am in such a rush that it feels like I hardly remember to breathe. Needless to say that this is freaking exhausting. After an hour of this my brain is just mush.
Of course, the obvious solution to this is to just take a break as soon as I notice me speeding up. I will try to do this more, but sometimes it feels like I can't. This unsolved bug will sit in my mind so that I can't stop thinking about it even if I'm not at the keyboard. "It must be solved. Now". Of course it doesn't, but that's what my mind is telling me.
In a few months I will probably be working as a full time dev again and until then I have to have solved this problem somehow if I want to do this any longer than a couple of years.
Ideally I want programming to be a meditative experience and feel refreshed afterwards instead of completely drained. This might be illusionary, but at least I would want it to be draining more like I've been on a good run, instead of feeling like being hit by a truck.
Anyways I'm wondering if any of you can relate to this and maybe has solved this in some way. Does this ever happen to you? What do you do to prevent this from happening? I appreciate any thoughts you have on this.
Don't let yourself get bottlenecked. The debug cycle can spiral out of control when you too fixated on one element.
When you feel that happen, take a five minute break and figure out some other part of the project you can spend time on that you know will work. Wasting hours on a stuck pig is frustrating, spending those hours instead making other progress let's you simmer on the issue.
Come back to it later with fresh eyes, and maybe it will be easier. If you hit the same wall after many attempts, maybe you have to find a different solution, and at least you got a ton of other stuff done.
The sunk cost fallacy is a lot worse when you've spend multiple sessions on the same issue.
It also helps when you can identify these problems early in the project cycle. Knowing what parts will work because you've done it before, versus new modules you haven't worked with, helps to plan testing of the unknowns early, even if they are used later in the project.
On large scale projects, I make sure to prototype the unknowns right at the beginning, and when I get stuck, I do easy work till I feel relaxed again. If I don't solve the first one, move on to the next, and next, unknown till I've been through each at least oonce. Then you'll have a road map of what works, and what's going to take the hard, head down, jam music on, I'm not stopping to piss till this works or I abandon it, sessions.
Then I know there are X number of those sessions in the project, and when I'm in that kind of mood, I tackle one. Some days you just want to bang out easy UI and functions, others you're ready to beat your head on the keyboard till that one thing works.
Other than that, I write a lot of test code around the problem so I can isolate exactly what where is. Then once it's fixed, I go back and strip it all out. Don't be afraid of spending time really understanding the issue before just doing brute force. In your example, if a module doesn't do what is expected, are you sure your connected to the module? Are the commands formatted correctly? Do you get any response from it or is it just dead or not loading? Can you write around it? Are there other modules available? Can you write your own code instead of using the module?
At the end of the day, what you said is right, step away and clear your head. I can't count the number of times I've come back to something I strained at for hours or days, only to solve it in 15 minutes a week later.
