Happiness is nothing more than good health and a bad memory. - Albert Schweitzer
Far too many people these days think that happiness and success is wealth. And then far too many people will realize the truth many years later, and usually after they fell ill, broken relationships and/or gone broke due to business failure or bad investment choice. By then, it may be too late for some.
To be clinical, there are different types of happiness. Absolute or relative happiness. Relative happiness is short-term, like buying your long-waited latest model of iphone. This gives you an instant gratification that perhaps you didn't experience for quite a while.
