Expecting the world to treat you fairly because you are a Good person is like expecting the lion not to attack you because you are a vegetarian. Think about it.
Whenever you feel low, always remember: you are braver than you believe, stronger than you seem, wiser than you think and life isn’t that bad. So cheer up!
Don’t make life’s critical decision on the basis of your mood. A mood is a dangerous state of mind because it can crush reason under the weight of feeling.
