William James

Believe that your life is worth living, and your belief will create the fact.

Genuine James. The canonical wording is 'Believe that life is worth living, and your belief will help create the fact.' The corpus text drops 'help' and inserts 'your' before 'life' — a very common softening. Attribution is not in doubt; the wording should be corrected to the published form if the corpus cares about exactness.

The art of being wise is knowing what to overlook.

Genuine. James's sentence is 'the art of being wise is the art of knowing what to overlook.' The corpus text drops the second 'the art of'. Attribution solid; wording is a light trim of the original.
