The correct answer is False.
Explanation
The thought is an action in which the individual can generate a mental image of a concept or idea. Likewise, thought allows to relate these ideas and create new ideas. Thought can have positive characteristics, for example, when we go to a job interview, our thoughts allow us to affirm that we are the best to perform in that position. However, there are bad thoughts, for example when we are on an airplane, surely we have ever thought that it could fall and cause a catastrophic accident. A peculiarity of thought is that everything happens in the mind of the individual and many times it can become reality, for example when we think about studying, traveling somewhere, calling your relatives, or just making food. However, not all thoughts can become reality, an example of this is when we are in trouble and just thinking that everything will happen, it will not change the situation if we do not take the necessary actions to change reality. Therefore, the correct answer is False, it is not possible to change all of life's problems just by thinking positively.
