So those who wished for some central cosmic purpose for us, or at least our world, or at least our solar system, or at least our galaxy, have been disappointed, progressively disappointed. The universe is not responsive to our ambitious expectations.
There have been occasions in my later life (I suppose as in most lives) when I have felt for a time as if a thick curtain had fallen on all its interest and romance, to shut me out from anything save dull endurance any more. Never has that curtain dropped so heavy and blank, as when my way in life lay stretched out straight before me through the newly-entered road of apprenticeship to Joe.
I never had one hour's happiness in her society, and yet my mind all round the four-and-twenty hours was harping on the happiness of having her with me unto death.
Other people are not here to fulfill our needs or meet our expectations, nor will they always treat us well. Failure to accept this will generate feelings of anger and resentment. Peace of mind comes with taking people as they are and emphasizing the positive.
Here is the vicious circle: if you feel separate from your organic life, you feel driven to survive; survival -going on living- thus becomes a duty and also a drag because you are not fully with it; because it does not quite come up to expectations, you continue to hope that it will, to crave for more time, to feel driven all the more to go on.
You're not going to be different ... you're going to be the same as you've always been; with doubts, everlasting dissatisfaction with yourself, vain efforts to amend, and falls, and everlasting expectation, of a happiness which you won't get, and which isn't possible for you.
William James once made an acute point about the relationship between happiness and expectation. He argued that satisfaction with ourselves does not require us to succeed in every endeavour. We are not always humiliated by failing; we are humiliated only if we first invest our pride and sense of worth in a given achievement and then do not reach it.
