Somewhere I heard this terms "Analysis Paralysis". You think and think and research and plan, and rethink, and just get more and more stuck.
It can happen.
Here are a couple of things I wrote in a notebook.
"When your passions lead you astray, go with what is needful and the Lord gave you to do. You may be just too lazy to follow the path laid out for you."
"Man's plans and design often don't work out. It is all in the Lord's hands. But lack of counsel and wisdom ruins most things."
I do not recall where the quotes come from, but they are not my own sayings, I know that.
