Sometimes the memory of people is indeed very short-lived and the good we do now might get forgotten very soon. You must do good anyway. In doing so you will find serenity and bliss. Happiness is a natural byproduct of doing good. Always maintain your positive attitude and thoughts, focus on doing GOOD always, have faith in the Almighty God and you will surely stay happy and blessed and also spread happiness around you.
Have a fabulous Wednesday.
