No matter what happens to us, we should stand up, look forward and act positively. Some people get tired of being nice and sincere because they are judged, deceived or abused by others. All the bad things you have passed through are now behind you, in the past. They are experiences from which you learned something. Act well and everything will be good. It doesn't make sense to dump the anger on the next person who appears in your life. That person is not responsible what happened to you. Life is a boomerang – those who treated you badly will receive the same thing at some point in their life. Let life take care of it. You breath, keep walking, stumbling and learning. Every setback is a learning experience that redefines the way you will act and proceed, and makes you a wiser, stronger and mature person.
