If you start a task, say yard work, and part way through you realize a tool is broken or inefficient... Stop.
Get the right tool and finish the job later.
If, instead of getting the right tool for a 15-minute job, you spend over two hours doing something manually, you lose any right to complain about the difficulty of the work. Five minutes to get the new tool saves you 2 hours of work. Your exhaustion and frustration is 100% your fault.
I have 0 sympathy for your stubbornness.
