Troubleshooting... the bane of my existence. I truly hate it. Most of the time when I troubleshoot I break the whole pedal. That's because it requires unsoldering so usually I burn off the pad, burn a capacitor, scratch the board... you name it.
Nobody is thrilled to find out that the circuit doesn't work, but it can be genuinely interesting or satisfying to solve the issue, even when it's something stupidly simple.
Maybe there's also something close to perversion in these hours spent at debugging circuits : delaying the pleasure in order to increase it ? Isn't it even more fun when you fight hard for something, and finally get it ?
Which one is the stronger feeling : being intimidated or bored by the troubleshooting process, or anticipating the moment of joy and fulfillment when it'll work ? The mindset will greatly shape our skills to build and debugg a circuit.
Being patient, observant, and willing to learn will make a difference. Hate and other bad feelings have to be overcome to get there.
I do think building stompboxes is a great way to learn these qualities, if you don't have them already.
Doing your best to make something with your hands, is a great source of pride and pleasure in itself.
Troubleshooting is usually the moment when you have to really care about the circuit, and follow its curves. If it works the first time, you don't get to know your stompbox as deeply, unless you really want to.
It's also the time to discover other people's perspectives and way of doing things, through forums.
If building stompboxes itself was a stompbox, troubleshooting would be the Gain knob.
