Everything has a beginning and an end.
Every mountain has a peak and every valley has a low point.
Every story has a beginning and an end.
Streets start at a certain point and end at a certain point.
A plant grows up and then withers, and then from it seeds another plant grows.
Seasons change, from autumn to winter, and then to spring and summer.
Storms are followed by sunshine.
Life has its ups and downs. One day looks bad, but the other day is great.
In the same way, problems don’t last forever. They get resolved sooner or later.
Every problem has a limited life span.
When you face a problem, don’t keep dwelling on it. Cheer up! Sooner or later the problem will either disappear, become irrelevant, or get resolved.
And even if the problem is difficult to solve, dwelling on it won’t help.
