There is a dilemma, to reconcile three time scales: in the short term, the economy; in the middle range, global well-being generally; and, in the long range, the environment.

You get [something] in your body that is the suffering or the problem, and then you [add] a second one, which is worry. In both cases, [it is] pointless.

Worries are pointless. If there's a solution, there's no need to worry. If no solution exists, there's no point to worry.

It's not the magnitude of the task that matters, it's the magnitude of our courage.

When hearing a door creak, the optimist thinks it's opening and the pessimist thinks it's closing.

The basic root of happiness lies in our minds; outer circumstances are nothing more than adverse or favourable.

We try to fix the outside so much, but our control of the outer world is limited, temporary, and often, illusory.
