IME as you approach the limit you can create an infinite number of tasks. The key for me is to pick tasks which balance expedience and bang for buck value, but if you are experiencing intense writers block then I see no problem with a task like "open editor."

Yea. It's like falling down the recursion with a stack size of 5. Do the task. Plan doing the task. Start planning doing the task. Plan starting planning doing the task...

Recursion isn't necessarily the problem per se - it's the sheer number of tasks. When you're at the level of "open terminal to project directory", it takes less time to do it than to write it down, but more importantly, you'll end up creating a 100 of those tiny tasks, and the overhead of keeping them up to date can easily suck all your motivation (and time) dry.
