We can consider successes and failures in our life as credit and debit entries of our happiness account. Every time we succeed in achieving our goal, we get credit in the form of happiness and every time we fail, we debit our happiness account. If we have enough credits of happiness, we can easily withstand some failures just like the person who has a million dollar bank balance, does not get disconcerted if he loses out on a few thousand dollars. However, the same loss can bring much grief to a person who has a very small balance in his account.
