1. People, who eat too much or do not eat at all, will not get happiness even after looking for it.
2. People, having too much sleep and those, who do not sleep at all, do not find happiness even after looking for it.
Exception for both: Old, sick and invalid people, because they cannot control their condition.
3. Liars and thieves will not get peace even after looking for it. Criminals and those who frame others for their crime, will not get peace even after looking for it.
To Sum Up: Sleep, food and industry should be optimum to get happiness. Sincerity, truthfulness and humanity breed peace of mind.
