Don't give up
Debugging is hard. It’s easy to spend an endless amount of time investigating or to get completely stuck.
Shrugging your shoulders or throwing your hands up will never solve the issue. It’s an opportunity to learn, and the path to the solution may not be linear. Build and use your array of techniques and skills to find a way forward.
Instead of giving up, change tactics. Sometimes that might mean working on something else or asking for help. It might even mean reverting or turning something off for a while.
This is a reminder for me and anyone else who sometimes gets stuck and disheartened.
