The past, and hope in failure

Make peace with your past so it won't spoil the present.
~ Advice

There are two cardinal sins from which all others spring: Impatience and Laziness.
~ Franz Kafka

Don't be discouraged by a failure. It can be a positive experience. Failure is, in a sense, the highway to success, inasmuch as every discovery of what is false leads us to seek earnestly after what is true, and every fresh experience points out some form of error which we shall afterwards carefully avoid.
~ John Keats
