But as the word satyagraha implies, Gandhi’s passivity was not weakness at all. It meant focusing on an ultimate goal and refusing to divert energy to unnecessary skirmishes along the way. Restraint, Gandhi believed, was one of his greatest assets. And it was born of his shyness: I have naturally formed the habit of restraining my thoughts. A thoughtless word hardly ever escaped my tongue or pen. Experience has taught me that silence is part of the spiritual discipline of a votary of truth. We find so many people impatient to talk. All this talking can hardly be said to be of any benefit to the world. It is so much waste of time. My shyness has been in reality my shield and buckler. It has allowed me to grow. It has helped me in my discernment of truth.

The highly sensitive [introverted] tend to be philosophical or spiritual in their orientation, rather than materialistic or hedonistic. They dislike small talk. They often describe themselves as creative or intuitive. They dream vividly, and can often recall their dreams the next day. They love music, nature, art, physical beauty. They feel exceptionally strong emotions — sometimes acute bouts of joy, but also sorrow, melancholy, and fear. Highly sensitive people also process information about their environments — both physical and emotional — unusually deeply. They tend to notice subtleties that others miss — another person's shift in mood, say, or a lightbulb burning a touch too brightly.

The key to flow is to pursue an activity for its own sake, not for the rewards it brings.
