Veronica, Pessimism is always living as if the cup is half empty, not half full.

Pessimism is definitely a poison to the roots of true happiness. It is important to realize we now have research on the healthy effects of optimism. Optimists are healthier, have more fun, and live longer than negative individuals. It’s your life. You choose.
