Details: This poster is a parody of a motivational poster. It shows a glass of beer and several shots around a pile of money. At the top it says 'Optimism' and at the bottom it says 'Doesn't matter if the glass is half empty or half full if you have a lot of glasses.'
Optimism is an inclination to put the most favorable construction upon actions and events or to anticipate the best possible outcome. Optimists consider the glass 'half full'.
