Don't hamper others happiness just because you are not happy.

Compare the luxuries with a neighbour to feel bad, compare the miseries with a neighbour to feel good.

Worry wastes time, envy wastes wealth.

Envy is the first emotion fools experience whenever they see a genius.

If people are jealous of you, it means you are worth something.

Society will question your reputation, but it will believe your defamation without question.

People would be happy to see you do better, but not better than them.

Secrecy is strength, what people don't know they can't spoil.

Those who can't match you will malign you.
