I am personally helped by the simple phrase of one monk. Very simple. He said:
“The Lord gives us strength for exactly one day.”
No need to think about the future yet. How you will rise tomorrow and what you will do. And what will you feel.
We must live this day and give everything as much as possible. Overcome the difficulties as much as you can. Make as many steps as you can on this particular day. Because for one day, power is always given.
And tomorrow … Tomorrow everything can change for the better. And the black clouds will gradually float over the horizon.
The main thing is to live a day.
