Just books in general? Professional development? Science Fiction? Politics? Can't go wrong with the classics like "Seven Habits of Highly Effective People" along with "How to Win Friends and Influence People." For motivation: "Can't Hurt Me" by David Goggins... it's impossible to read that book and come up with a good excuse why you cannot achieve your goals.

I love Goggins! That's a great book. So hard to believe, but there's documented evidence for his achievements. Unbelievable.
Based on your Best Books list, check out David Goggins book 'Cant Hurt Me'. I found him through a podcast he did with Joe Rogan and it resonated with me on a deep personal level. It ultimately inspired me to change my life: I lost 50 lbs since, got a raise and promotion at work and travelled more in 2019 than the last 5 years.
