If life becomes hard to bear we think of a change in our circumstances. But the most important and effective change, a change in our own attitude, hardly even occurs to us, and the resolution to take such a step is very difficult for us.
Ludwig WittgensteinSuppose someone follows the series "1,3,5,7, ..", and in writing the series 2x+1; and he asked himself "But am I always doing the same thing, or something different every time?" If from one day to the next someone promises: "Tomorrow I will give up smoking", does he say the same thing every day, or every day something different?
