Therapists who deal with patients who suffer from depression teach their patients to keep track in a notebook of the positive experiences of that day. The hope is that by keeping them present in their immediate memory that there will be less room there to focus on being sad. I believe this is great advice for anyone to follow not just the clinically depressed.
Life starts for humans surrounded by hope and optimism. There are extended family members who eagerly await our arrival and committedly tend to our helpless little forms. As we grow we experience comfort at the care of family, friends and educators. We learn to seek out the best in life and dedicate extensive amounts of time to building happiness. Joy seems to be all around us as we build upon our extensive repertoire of collected happy memories.
We all have it. It is buried, sometimes just bellow the surface of some unpleasant experience. It is our source of joy. It is our inspiration for happy moments. Perhaps what we need is just a little reminder. What we perhaps need is to see it in writing, the words, "Amazing" and "fantastic" attached to the everyday experiences of our lives. Perhaps if we see it in our own hand writing that life is worth living then we will not sulk or despair but instead we will rejoice.
