Will entrepreneurship make me more anxious than debugging?
Let's put it this way: these two anxieties are not even in the same league.
The anxiety of debugging is when you know for sure something is broken; it's there, you just haven't found it yet. It's like a very complex lock, and you are the locksmith. Although you might try many keys and spend a lot of time, you clearly know your goal is to "open this lock." You're dealing with code, logic, something concrete. This process might drive you crazy, make you want to smash your keyboard, but once it's fixed, it's over. You can breathe a sigh of relief and go grab a coffee. This anxiety is technical, with a clear endpoint.
The anxiety of entrepreneurship is when you're standing in a pitch-black wilderness, not only having to build a city from scratch by yourself but also convincing others to live in it, all while finding food (income) to sustain everyone. You're not anxious about a "bug," but about everything: Is the product direction right? Can we pay salaries next month? Why aren't customers buying? What new moves are competitors making? Will anyone invest? None of these questions are 100% within your control, and none have a standard answer.
So, debugging anxiety is "point-like," short-term, and solvable. Entrepreneurship anxiety, on the other hand, is "area-like," pervasive in every corner of life, and continuous. It's not "Can I solve this problem?" but "Can we survive?"
Debugging might keep you up for a few nights at most, but entrepreneurship might make you feel that sleep itself is a luxury for a very long time. Of course, the immense sense of accomplishment from creating value from nothing is something debugging can't compare to.
