Fear and pain are the greatest teachers you will have during your life because nobody forgets the lessons they teach. Not only that, fear and pain can guide a lot of people’s future behaviour because people avoid doing things that attract fear and pain back into their lives. For example, the number of people who remain single is because of a bad romance.

The thing everyone should take into consideration is that fear and pain are based inside your mind, historical by nature, and you have the power to overcome them.
P.S. This post is not about physical pain because that’s only a temporary setback.
