Being a Pessimist

The older I get, the more I realize how easy it is to be negative. I found myself being more of a pessimist and bringing my negativity everywhere. If we bring our burden of stress from school or from work around, doesn't it snowball into a bigger ball or stress, anger, anxiety and negativity?
It's so easy to spread negativity and to push your anger on others when you're in a bad state of mind but often you have to step back and look at the bigger picture.
How does this negativity reflect on my character? How is my negativity hurting those who love and care about me?

It's important to step back and look at the bigger picture and remind yourself, it is easier to love than to hate.
