Concern for man himself and his fate must always form the chief interest of all technical endeavors, concern for the great unsolved problems of the organization of labor and the distribution of goods-in order that the creations of our mind shall be a blessing and not a curse to mankind. Never forget this in the midst of your diagrams and equations.
In the first place, you shouldn't believe in promises. The world is full of them: the promises of riches, of eternal salvation, of infinite love. Some people think they can promise anything, others accept whatever seems to guarantee better days ahead, as, I suspect is your case. Those who make promises they don't keep end up powerless and frustrated, and exactly the fate awaits those who believe promises.
For when you see that the universe cannot be distinguished from how you act upon it, there is neither fate nor free will, self nor other. There is simply one all-inclusive Happening, in which your personal sensation of being alive occurs in just the same way as the river flowing and the stars shining far out in space. There is no question of submitting or accepting or going with it, for what happens in and as you is no different from what happens as it.
For this our task hath Fate spun without fail to last for ever sure, that we on man weighed down with deeds of hate should follow till the earth his life immure. Nor when he dies can he boast of being truly free.
What a fate: to be condemned to work for a firm where the slightest negligence at once gave rise to the gravest suspicion! Were all the employees nothing but a bunch of scoundrels, was there not among them one single loyal devoted man who, had he wasted only an hour or so of the firm's time in the morning, was so tormented by conscience as to be driven out of his mind and actually incapable of leaving his bed?
There is indeed one element in human destiny that not blindness itself can controvert: whatever else we are intended to do, we are not intended to succeed; failure is the fate allotted. It is so in every art and study; it is so above all in the continent art of living well.
