As a variation on that theme, sometimes the reason I don't want to do it is because I don't actually know how to do it, or even what to do. While telling myself it should be easy.
Then when I rephrase it as "I have to make this clearer first", or "what's a first step to learn how to do this" or so, I stop procrastinating.
This is why it takes me a day or two to orient myself towards starting a big task. The sooner I get to the ”I have to make this clearer” part, the sooner I have a roadmap, and the sooner I start coding.
The problem is essentially in how tickets are written.
