Daniel Kahneman

The effort invested in 'getting it right' should be commensurate with the importance of the decision.

If people are failing, they look inept. If people are succeeding, they look strong and good and competent. That's the 'halo effect.' Your first impression of a thing sets up your subsequent beliefs. If the company looks inept to you, you may assume everything else they do is inept.

It's a wonderful thing to be optimistic. It keeps you healthy and it keeps you resilient.

Nothing in life is quite as important as you think it is while you're thinking about it.

When you analyze happiness, it turns out that the way you spend your time is extremely important.
