The trough is not terrible, what is terrible is that we do not have the courage to face setbacks and the ability to return to the peak. When you look at yourself at the lowest point, you will understand the height you can reach; when you look around at the lowest point, you will see the path you really want to take. Life is like the alternation of day and night, and after darkness comes light. Don't be afraid, face setbacks, don't be afraid of the trough, everything will pass.
