The effort to feel happy is often precisely the thing that makes us miserable. And that it is out constant efforts to eliminate the negative - insecurity, uncertainty, failure, or sadness - that is what causes us to feel so insecure, anxious, uncertain, or unhappy.

Uncertainty is where things happen. It is where the opportunities - for success, for happiness, for really living - are waiting.

True security lies in the unrestrained embrace of insecurity - in the recognition that we never really stand on solid ground, and never can.

What made Leonardo da Vinci, Thomas Edison and Albert Einstein such creative geniuses? It wasn't reading books or watching YouTube talks about How To Be More Creative, that's for sure... If startling insights could be systematically arrived at, they wouldn't be startling. The best you can do is to create a conducive environment: put in the hours; take time to daydream; avoid mind-corroding substances.

Through positive thinking and related approaches, we seek the safety and solid ground of certainty, of knowing how the future will turn out, of a time in the future when we'll be ceaselessly happy and never have to fear negative emotions again. But in chasing all that, we close down the very faculties that permit the happiness we crave.

The effort to try to feel happy is often precisely the thing that makes us miserable.

Ask yourself whether you are happy', observed the philosopher John Stuart Mill, 'and you cease to be so.' At best, it would appear, happiness can only be glimpsed out of the corner of an eye, not stared at directly.
