Values are good things only if they are good values.
Never do anything for another with the expectation of gratitude. The expectation itself turns the gift into an exchange and suggests a debt is owed you.
You don't have to be sick to get better.
What will matter is not your success but your significance.
Don't sacrifice a good life for a good time.
It is better to be unsuccessful pursuing a significant goal that being successful attaining an insignificant one.
