The correlation between gratitude and increased well being is pretty amazing; powerful and fundamental magic. Kelly first turned me on to Gratitude Stones; using a object to spark grateful thoughts and improve your life. 
Elect small, beautiful items, like stones or coins, as gratitude items. Slip them into places your cross often; your coat pocket, make-up bag and cookie jar to name a few. Anytime you meet one of your gratitude items in daily life, take a moment to think of something you are grateful for. Incorporating gratuitous exercises like this has been proven in multiple studies to produce positive effects.
My 1959 Mexican Peso depicts José María Morelos, an important Mexican historical figure from the 1700-1800's. He was been a Catholic priest who took up the cause of the Mexican Independence movement. The rim of the coin is inscribed with the words "independencia y libertad". Independence and freedom are two things I am very grateful for.
