The point is that the fate of the whole world depends on you. You think you're a little person who doesn't depend on anything, but you're wrong. One of your good and right actions can change the whole world.
The joy of life comes from the realization that God is the order and everything goes according to plan. Faith in God is, first of all, trust in God. When you trust God, your fear disappears. Fear is a sign of distrust of Providence.
The universe knows how best and gives you what you need and when you need it. Your task is to take what is given and look for the benefit of it. The worst thing you can do is close your eyes in fear and try to escape from reality.
Don't feel sorry for yourself, don't feel sorry for yourself under any circumstances. If you feel sorry for yourself even for a second, you will fall into despondency, and you will strangle yourself with anguish. There is no reason for self-pity, you are the blind weapon of fate. You do what the rock tells you to do.
That last problem, which cannot be avoided or overcome, is your cross, your meaning of life, your infinite source of happiness and joy. Love your enemy-then accept your fate and joyfully bear your cross.
