@greathpath it's really a great quote I thinks our behaviour is so much important for happiness of we behaved like gentle than trust me it's our happiness 10 to 100 percent can reached it. Our life is always depends on our behaviour. I seen few of familys are never get happiness just beacuse them behavior for them each other like they always fighting for little issues which is really wronged. If you politely behave than you never to suffered from sadness. Behavior is the most of great key of your happiness you need to know how can you used it.
Big thumbs up
