Ceaseless optimism about the future only makes for a greater shock when things go wrong; by fighting to maintain only positive beliefs about the future, the positive thinker ends up being less prepared, and more acutely distressed, when things eventually happen that he can't persuade himself to believe are good.

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 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.

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

It is illuminating to note, here, how the daily rituals and working routines of prolific authors and artists - people who really do get a lot done - very rarely include techniques for 'getting motivated' or 'feeling inspired'. Quite the opposite: they tend to emphasise the mechanics of the working process, focusing not on generating the right mood, but on accomplishing certain physical actions, regardless of mood.

Who says you need to wait until you 'feel like' doing something in order to start doing it? The problem, from this perspective, isn't that you don't feel motivated; it's that you imagine you need to feel motivated. If you can regard your thoughts and emotions about whatever you're procrastinating on as passing weather, you'll realise that your reluctance about working isn't something that needs to be eradicated or transformed into positivity. You can coexist with it. You can note the procrastinatory feelings and act anyway.

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