The professor began his lesson by taking a glass with a small amount of water in his hand. He held it up so that everyone could see it and asked the students:

How much do you think this glass weighs?

The audience whispered animatedly.

- Approximately 200 grams! No, 300 grams, perhaps! Or maybe all 500! – began to be distributed answers.

“I really won't know for sure until I weigh him. But now it is not necessary. My question is this: what happens if I hold the glass like this for a few minutes?

- Nothing!

“Indeed, nothing terrible will happen,” the professor replied. - And what will happen if I hold this glass in my outstretched hand, for example, for two hours?

Your arm will start to hurt.

What if it's all day?

“Your hand will go numb, you will have a severe muscular disorder and paralysis. You may even have to go to the hospital,” said one of the students.

- Do you think the weight of the glass will change from the fact that I hold it all day?

- Not! students answered in confusion.

- What should be done to fix this?

Just put the glass on the table! one student said cheerfully.

- Exactly! the professor replied cheerfully. “So it is with all life's difficulties. Think about some problem for a few minutes and it will be next to you. Think about it for a few hours and it will suck you in. If you think all day, it will paralyze you.

You can think about the problem, but as a rule, this does not lead to anything. Her "weight" will not decrease.
Action is the only way to deal with a problem.
Solve it, or put it aside. There is no point in carrying heavy stones in your soul that will paralyze you.
