Most people are blind to their own failings. A new perspective due to a sudden insight can change your life; I think some drugs allow for an increase in the frequency of those insights.

I don't think I have reached a higher level necessarily, but I used to be insecure, depressed, negative, timid, lazy, and immature just to start. Now I am confident, assertive, positive, and strong-willed. I am a totally different person. I'm definitely not perfect, but I'm not done. I have many flaws, and I'll find many more. This is a lifelong process.
