Of the big three founders of psychoanalysis, Adler was the only one who knew what he was talking about. I put off reading him for a long time because I expected him to be just another Freud or Jung coming up with confused and harmful conceptions of the human mind but I was pleasantly surprised to learn otherwise.

Some important things that Adler was right about:
- A person's character, personality, and behavior are not inherited or congenital.
- The effects of the endocrine system is largely a myth created to perpetuate popular prejudices (such as the four "humors") that have persisted since antiquity, and there is no scientific evidence to prove that our glands control our minds in any way.
- Interactions with other humans especially in childhood forms the roots of how we perceive ourselves and interact with the world, but we're also not doomed to stay that way if we put in work.
- Psychological differences between men and women are artificial and young children are especially aware of this, but as we grow we accept the absurdities that society leads us to believe about gender. Until we reach true equality between the sexes humanity will always suffer.
- Through education and parenting reform we can change human behavior to better serve humanity, but neither parents nor teachers have the adequate psychological training or education to raise a child properly.
