People tend to dwell more on negative things than on good things. So the mind then becomes obsessed with negative things, with judgments, guilt and anxiety produced by thoughts about the future and so on.

Thoughts are fine when you don't confuse them with who you are, and then thoughts are not a problem. Thinking is a wonderful tool to create things in this world. It only becomes problematic and a source of suffering when you confuse thinking with who you are.

If small things have the power to disturb you, then who you think you are is exactly that: small.

The power for creating a better future is contained in the present moment: You create a good future by creating a good present.

People don't realize that now is all there ever is; there is no past or future except as memory or anticipation in your mind.

The mind is a superb instrument if used rightly. Used wrongly, however, it becomes very destructive. To put it more accurately... you usually don't use it at all. It uses you.
