Thinking more than others about our own thoughts is not self-centeredness. It means that if asked whats on our mind, we are less likely to mention being aware of the world around us, and more likely to mention our inner reflections. But we are less likely to mention thinking about other people. – Elaine N. Aron

No matter how hard you work for success if your thought is saturated with the fear of failure, it will kill your efforts, neutralize your endeavors and make success impossible. – Baudjuin

Thought is a kind of opium; it can intoxicate us, while still broad awake; it can make transparent the mountains and everything that exists. – Henri Frederic Amiel
