"Do what you can with what you have."
I have lived by this rule for a while, and it has led to major mistakes. It should say, "Do the most important thing you can with what you have."
This alternate statement leads to decision making. It leads to asking deeper questions.
Maybe the question, "What is the most important thing I can do with what I have?" is more important than the premise.
And maybe that question leads to more bigger questions, like, "do I really care about this?" or, "is this really important, or do I just want it to be?"
And maybe, asking the right questions is more important than having the right answers.
