This book is annoying courage: Adler's philosophy class, the father of self-motivation. (Japan) A Historical Review of Ichiro Shore in Koga.
Here is the first cognition of subversion, from cause to teleology. Nowadays, many psychological self-help books will say that your current problems are influenced by what happened in your childhood, which is the cause theory.
Teleology says that you want to achieve a goal, so that you can find events that can assist this goal in the past events, thus confirming your correctness.
The point here is that you won't change the cause theory easily, because the past has become a fact, but the teleology is different. It is subjective, changing the purpose and changing the result.
The courage to be hated is relative to being a good person. We can't make everyone like ourselves. Trying to please everyone is a passive lifestyle.
A very important concept mentioned in the book is called subject separation. Everyone's topic is different. Only by doing your own topic well and not interfering in other people's topics will life become active.
When you stop focusing on everyone you meet, you will focus on your own life and let it fully realize your life value.
In the past, when we talked about ourselves, we thought of doing whatever we wanted and what we didn't want to do, but in fact that was not true freedom.
The above is only physical freedom, and our deeper freedom should be spiritual freedom. Not bound by external cognition, take the initiative in life and dominate your own life.
Don't be afraid of being hated, but go ahead, don't go with the flow, but go with the flow. This is human freedom.
