If the problem can be solved why worry? If the problem cannot be solved worrying will do you no good.

We who are like senseless children shrink from suffering, but love its causes. We hurt ourselves; our pain is self-inflicted! Why should others be the object of our anger?

Focus on the task at hand giving it your complete attention and effort. Only move on when complete. This can eliminate stress and worry.

That may solve the problem.

I can't be part of your equation. But I rather want to solve your problems.

If you have problem in your life, help enough people to solve their problem. You will get rid of your problem in short time. It works.
