All that is required to become an optimist is to have the goal and to practice it. The more you rehearse optimistic thoughts, the more 'natural' and 'ingrained' they will become. With time they will be part of you, and you will have made yourself into an altogether different person.

Find a happy person, and you will find a project.

When we are fully mindful of the transience of things - an impending return home from an overseas adventure, a graduation, our child boarding the school bus for the first day of kindergarten, a close colleague changing jobs, a move to a new city - we are more likely to appreciate [be grateful for] and savor the remaining time that we do have. Although bittersweet experiences also make us sad, it is this sadness that prompts us, instead of taking it for granted, to come to appreciate the positive aspects of our vacation, colleague, or hometown; it's 'now or never.'

It turns out that the process of working toward a goal, participating in a valued and challenging activity, is as important to well-being as its attainment.

People prone to joyful anticipation, skilled at obtaining pleasure from looking forward and imagining future happy events, are especially likely to be optimistic and to experience intense emotions.

Write down your barrier thoughts, and then consider ways to reinterpret the situation. In the process, ask yourself questions like... What else could this situation or experience mean? Can anything good come from it? Does it present any opportunities for me? What lessons can I learn and apply to the future? Did I develop any strengths as a result?

I prefer to think of the creation or construction of happiness, because research shows that it's in our power to fashion it for ourselves.
