I strongly recommend Seneca's On the Shortness of Life. It's one of the best books I've read, and at the very top on the subject of Carpe Diem.

One of the best books I ever read was from a dude named Seneca (a stoic Roman philosopher).

The book is called On the Shortness of Life: Life is Long if You Know How to Use it[0].
