The question arises: if the crisis is a continuous positive, why, the bulk of people, facing it, is far from happy with the result? There is one "but", consisting in the perception of what is happening. The well-known expression says: "if you can not change the situation - change your attitude towards it"!
The thesis about the materiality of thoughts implies the fact that negative thoughts are embodied in negative events and vice versa, that is - what is inside a person, then outside. A look at any incident from the point of view of the positive frees you from the need to be nervous, to panic and fixate on the problem, and the problem itself ceases to be such, and turns into a category of tasks that, as you know, have solutions.
Thus, instead of choosing the role of the victim, excluding the possibility of somehow influencing events, a person sees what is happening from the position of the owner, and if he himself created a crisis in his life, then, taking responsibility for himself and changing his thoughts, he can solve the situation in your favor!
So it turns out that the path to progress consists of a series of certain obstacles, overcoming which you can get a new useful experience and expand your consciousness. How else? Is it possible to achieve success in any case without suffering a defeat at some point and not drawing conclusions from it?
