I passionately believe that's it's not just what you say that counts, it's also how you say it - that the success of your argument critically depends on your manner of presenting it.

If optimism is important, it's because many outcomes are determined by how much of it we bring to the task. It is an important ingredient of success. This flies in the face of the elite view that talent is the primary requirement of a good life, but in many cases the difference between success and failure is determined by nothing more than our sense of what is possible and the energy we can muster to convince others of our due. We might be doomed not by a lack of skill, but by an absence of hope!

The only way to be happy is to realise how much depends on how you look at things

Everyone wants a better life: very few of us want to be better people.

Our sadness won’t be of the searing kind but more like a blend of joy and melancholy: joy at the perfection we see before us, melancholy at an awareness of how seldom we are sufficiently blessed to encounter anything of its kind. The flawless object throws into perspective the mediocrity that surrounds it. We are reminded of the way we would wish things always to be and of how incomplete our lives remain.

Status Anxiety: A worry, so pernicious as to be capable of ruining extended stretches of our lives, that we are in danger of failing to conform to the ideals of success laid down by our society and that we may as a result be stripped of dignity and respect; a worry that we are currently occupying too modest a rung or are about to fall to a lower one.

Our minds are susceptible to the influence of external voices telling us what we require to be satisfied, voices that may drown out the faint sounds emitted by our souls and distract us from the careful, arduous task of accurately naming our priorities.
