This emotion speech by Chip Conley gives two practical equations that can be used for resolving any form of mental anguish or depression.
The formulas included by Chip are quite simple to follow and most emotional problems can be entered. For instance, if one is suffering from anxiety, they could enter such into the variable section of the formula in order to come up with what's causing it. The formula will also display what is helping aid the situation and will therefore make one feel thankful for what they have.
Although the formulae provided by this emotion speech will help, it is up to the individual to decide whether they want to take it into their own hands and better their life.
