Ignore negative people and move on from them when you must.
There are some people that are so entrenched in seeing the negative side of things that they leave zero room for positive things to grow. People like this inhabit our families, work environments and social circles. It can be emotionally draining just being around them, and you must be careful because their negative attitudes and opinions are venomous and contagious. Negativity perpetuates itself, breeds dissatisfaction and clutters the mind. And when the mind is cluttered with negativity, happiness is hard to come by.
