If you're around it continually, especially as a child, it will contaminate your perceptions, beliefs, and behaviors as an adult. But you can unlearn negativity. Here's how to turn negative attitudes and behaviors into positive ones and begin leading a happier life.
Awareness is key .
First recognize that you have a tendency to be negative, although perhaps only in certain situations. If you don't, your negative feelings will gain power and overtake you. Once you acknowledge your negativity, realize you always have alternatives and then choose to change. Positive people recognize that they have options. What really sets positive people apart is how they deal with changes they don't initiate.
