The details matter until they don't.
If you're not doing the basics 80% of the time, then there is no need to accumulate more information. If you're not very good at the basics, all that says is that you're not very good at implementing the simple information that you have already.
If you think that you need more details, more answers, more information then you're sadly mistaken.
That will only inhibit your ability to take action if you're already having a hard time with implementation.
Keep it simple and do simple really damn good 80% of the time.
