Reading a book by someone whose life you want to be living, being around people who are healthy and productive and creative and prosperous and full of life will dramatically affect your mindset. Listen to audiobooks from the great ones. Read great autobiographies of people like Elon Musk or a Steve Jobs or a Wozniak. Read books on positive psychology. And the larger point is because you become who you hang around with. And so if you hang out with Elon Musk and if you hang out with the great business-builders, even if you don’t know them through their books, through their works, their thinking will leave what I call residual wisdom on your choices as you go through your day. Their thinking, their sharing their influences, their ways of doing, their daily rituals will leave residual wisdom on your mindset and your behavior in every remaining hour as you go through your day.
