"Knowing what to leave out is just as important as knowing what to focus on." - Warren Buffett

— from The Mind in the Cockpit · Win Your Inner Battles: Defeat the Enemy Within and Live With Purpose by Darius Foroux

In the book

Reflection is the machine that turns raw experience into insight — experience alone teaches nothing; reflected-upon experience teaches everything. Insight favors the prepared mind, coming to the one who has already done the patient work and is now, at last, at rest; and much of clear thinking is subtraction, since knowing what to leave out matters every bit as much as knowing what to focus on. Keep a box of mental tools close at hand for all of this, and hold your thinking to its purpose: my thinking, William James said, is first and last and always for the sake of my doing — a mind that only spins is not thinking, it is idling. — The Mind in the Cockpit
