Being 100% truthful to myself, my mind is the only mind that does exist, as everything happens in my mind, and I'm the only person that can feel. If I disagree with such an interpretation, then I'm lying to myself.
Being afraid to admit high self confidence is having low self esteem.
Accepting the world as a product of my mind, disables it from ever being able to catch up to me, much less get ahead of me. A perfect example is I typed these words after thinking them, and now the world can read them.
It's harmless to imagine negative thoughts and never take negative actions as a result of those thoughts, this gives me unlimited potential to use my imagination as a tool to balance my positive physical experience with negative thoughts. I can think negative and experience positive, for balance.
