you'd be better off reading something like Marcus Aurelius' Meditations instead, or some of the other classics.

The Mistborn trilogy by Brandon Sanderson (recommended to all fantasy fans)

Not only a description of the Stoic philosophy, which is, unfortunately, not very well known today, but also a great practical guide to a variety of techniques that can be included into daily activities easily, and will increase happiness.

The book is a great encyclopedia of exercise that can be performed without or with minimal equipment.
