I started my personal development journey in 1997. The first thing I did was read a lot of books. The first book I read was Feel the Fear and do it Anyway. It was an eye-opener for me.
I’ve read over 1000 self-help books in my lifetime. I can tell you from experience that reading self-help books will temporarily change the way you feel, but they won’t change who you are. To change yourself, you have to change your nervous system; you have to reprogram your entire being. Let’s say you have a negative emotion you want to remove.
You could try using the Emotion Code or body code program to do this. You will not permanently remove a lingering negative emotion by reading a self-improvement book; You have to engage your entire body to make changes in yourself. You have to change your physiology and personal beliefs to do this.
Some people think personal development is a waste of time or isn't even possible because it can't be measured.
