One of my friend used to say that he always compares himself with what he was the previous day (and he doesn't compare himself with anyone else), so he is continuously trying to improve based on his own individual condition and goals . Life is all about our learning and the experiences we accumulate each day, and each of us are unique with our own talents and skills. There are ample examples which shows that even successful or rich people, need not be the most happiest people, as it is all comes down to our perspective of life. One way to attract happiness to ourselves, is through compassion on both our own selves and for others, and if we try to be kind to others even with a simple smile, that will certainly bring happiness back to us.
