We have to fight them daily, like fleas, those many small worries about the morrow, for they sap our energies. We make mental provisions for the days to come, and everything turns out differently, quite differently. Sufficient unto the day. The things that have to be done must be done, and for the rest we must not allow ourselves to become infested with thousands of petty fears and worries.
If one burdens the future with one's worries, it cannot grow organically. I am filled with confidence, not that I shall succeed in worldly things, but that even when things go badly for me I shall still find life good and worth living.
