Develop a positive outlook on life and towards others

Use awareness and observation to deal with negativity.
It is important to understand that negativity is simply one trait. Step back and understand why someone is behaving negatively. They might be hurting, they might need help. Understand them without judgment.

Accept when you don’t have the skills to solve a problem.
If you don’t have the energy or experience to help someone, guide them to a person who could help them better.

Become self-aware.
Evaluate your internal negativity. Address and amend petty and negative thoughts and words that brew in your mind.
