Spiritual Experience

Character cannot be developed in ease and quiet. Only through experience of trial and suffering can the soul be strengthened, ambition inspired, and success achieved.

Don't worry when you are not recognized, 

but strive to be worthy of recognition.

Good judgment comes from experience, and a lot of that comes from bad judgment.

There is only one corner of the universe you can be certain of improving, and that's your own self. 

There is nothing impossible to him who will try.
