For me both are necessary and also both must be amounted moderately because too much of the two becames too bad and instead of happiness, it might bring sadness and greed. For me we can still acquire happiness through doing leisure and entertainment like playing games such as basketball, volleyball etc. I am also into playing online games to make myself happy specially now that I am into an online casino which I do enjoy and it totally makes me happy because of the varieties of games I can play plus the bonus rewards I can have making it more fun to play gambling and online casino to make myself happy.
