Charles Duhigg "The Power of Habit" and Kelly McGonigal "The Willpower Instinct" both greatly impacted my perception of people's actions and ways of life. Currently reading "Thinking Fast And Slow" and it has the same effect on me.

Jordan B. Peterson "12 Rules for Life: An Antidote to Chaos" made me more proactive and helped to summarize some past experience.

Richard Feynman "Surely You're Joking, Mr. Feynman!" awesome book, about awesome life of awesome person.
