Peace is not weak. Standing up to a tank is harder than dropping a suicide bomb

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

When you see those in healthcare who don't get this burn-out, they are very motherly, fatherly, or loving and attentive with the patients. [These] wonderful caretakers, doctors, and nurses don't get as much burn-out as people who are more defensive of the feelings and suffering of others.

Although the optimist may be a little giddy when foreseeing the future, telling himself that it will all work out in the end when that isn't always the case, his attitude is more fruitful since, in the hope of undertaking a hundred projects, followed up by diligent action, the optimist will end up completing fifty. Conversely, in limiting himself to undertake a mere ten, the pessimist might complete five at best and often fewer, since he'll devote little energy to a task he feels to be doomed from the start.

When faced with adverse circumstances, if you can do something, do it and there is not need to worry. If you can't do anything, then there is no point to worry. So in either case, worrying is an added suffering. But this does not mean of course that we should not be unhappy about injustice, abuse and other kinds of behavior that brings suffering upon others.

Authentic happiness is not linked to an activity, it is a state of being.

I don't often get into a bad mood, since it does not help anything and clouds my judgment, but I can certainly see that sometimes things go terribly wrong. We need to understand the reasons for this and work towards building new conditions that will bring about better circumstances.
