This video clip discusses the importance of mindfulness and working diligently upon our internal worry processing system. Being cognizant of the stressors in your life and putting your hardships into a larger perspective can help you face issues with a level head. This is essential in order to stop your worries before they stop you.
Not only is this an important process in establishing an internal sense of control, this video argues that stoic mindfulness is the key to the pursuit of happiness. It might be optimistic to suggest that curbing excessive worry can single handedly make a person happy, but it is surely a great start to having a better frame of mind.
