No matter what the situation is or what you are going through,always be positive. Try to be positive in the negative society of today.
Never feel shameful to be at the right path or to talk about a good aspect of life.
For being positive most important thing is that your company is right. Your friends which are the most important part of your life, should b cheereful and uplifting. It is a famous quote "A man is known by his company" and it's right to this aspect that they influence you to a greater extent. If they are positive then you'll be positive so you should choose them wisely.
Never ever allow negativity take over you. If someone says bad about you, reply with a good behavior and try to that thing in the best possible way.
Never surround yourself with negativity,try to escape that and talk about this to people. If you remain positive and stuck to your point of view then one day people around you will change for sure. But for this you have to take the first step. BE THE CHANGE YOU WANT TO SEE IN THIS SOCIETY. You should try to help others cope with their negativity.
And remember
ONCE YOU REPLACE NEGATIVE THOUGHTS WITH POSITIVE ONES, YOU'LL START HAVING POSITIVE RESULTS"
