There are some fantastic books already listed, some personal favourites include Lolita, Status Anxiety, Mao’s Last Dancer, and The Contenders.
I’ll add to the already in depth list:
Hacking Your Education (Dale J. Stephens)
Stephens is the founder of UnCollege and author of Hacking Your Education. The book challenges people to learn differently, deviating from the traditional path of tertiary education. It doesn’t displace the notion of traditional education, instead its aim is to depict that there are many other alternatives and that learning is about picking what is right for you; figuring out how to create an education from all possible avenues: university or otherwise.
The Power of Habit (Charles Duhigg)
Duhigg drills down life to this. We are all habitual people and our lives are run by a series of mini routines which are triggered by a cue and end with a reward. Identify the trigger and you can detour to a different, more positive routine. The idea (and Duhigg backs this up by referencing scientific studies of mice) is that old routines can never be obliterated but you can write over those negative routines by instituting a positive routine instead.
The Consolations of Philosophy (Alain de Botton)
This is a great book for those that want an introduction to Philosophy. It’s a short book and suitable for all ages, I believe I read this back in high school. The book introduces some of history’s greatest minds. Bringing together their ideas and relating them to the modern perspective. Each chapter (6) of the book focusses on a particular philosopher and idea: Socrates offers us consolations for unpopularity; Epicurus, consolations for being poor; Seneca, consolation for frustration; Montaigne, consolation for inadequacy; Schopenhauer, consolation for unrequited love; and lastly, Nietzsche, a consolation for difficulties.
Sure, there are other philosophers De Botton could of touched on. But it’s a fun, interesting, book nonetheless!
