Many people tend to voice negative feelings, to take energy and package it in ways that echo what they do not want to feel. Perhaps you do this. Perhaps you ask how to find good where you are. Its never too late to shift your perspective.
1) Decide to find advantages in every experience.
2) Choose to drop the negative spin on things.
3) Decide you no longer choose to suffer.
4) Realize you need not perpetuate every pattern.
5) Know you are more than apparent conditioning.
6) Accept that you can shift behaviour by choice.
