A person is basically only as happy as they make up their mind to be! When we think about good things we tend to increase our general and over all happiness. This is not a theory or some self help statement. This is scientifically proven. As humans, we thrive on good feelings and tend to lose our sense of well being with bad feelings. So, if a person was to practice or train daily the act of replacing negative thoughts and feelings with more productive positive ones, then your general happiness will increase and your ability to achieve more, give more and do more will increase. Try it. It actually works! But it is work and it is up to YOU!!
