I hate the guru talks about mindset. How everything is 90 mindset and you never learn anything from them useful for your own case, because usually those gurus are too much of generalists.
However, a simple strategy we can all use is directing our focus by asking questions. What would you like to experience this Monday?
What attitude will serve you today? This might not help you a lot, but at least you might find the right battles to fight and ignore everything unrelated to your long-term goals.
