Maltz came to the conclusion that our self-image is the cornerstone of our mental state, and therefore of all the successes and failures that happen in our lives as a result.
most people let past experiences define them in a negative way. Therefore, they end up behaving in a way that’s not coherent with who they really are, but only with who they “think” they are
The thing to point out is that our brain doesn’t distinguish between imagination and reality; instead, it acts based on the information we send it through our thoughts. Thus, we can imagine a new version of ourselves through our attitude and interpretation of various situations, “describing” the new paradigm to our brain which, in turn, will find a way to make that image come to fruition. However, to reach that new level, we must have a clear picture of the person we want to be.
taking time to relax yields tremendous benefits when it comes to dehypnotizing ourselves from wrong thoughts and convictions. All it takes is thirty minutes a day: find a comfortable spot and let go of all the tension that piled up in your muscles throughout the day
The continuous dwelling on past failures doesn’t simplify the process of getting better; on the contrary, it tends to perpetuate the behavior that you want to change. In a nutshell, it is self-destructive.
