On the Shortness of Life was written by Seneca around the year 49AD. He argues that we waste so much time because we do not properly value it. We expend great effort in protecting other valuables such as money and property, but because time appears intangible, we allow others to occupy it and take time away from us. Wise people, on the other hand, understand that time is the most valuable of all resources, and with effort can free themselves from external control to engage in meaningful introspection and create an intentional life.

Of a Happy Life is an essay written by Seneca around the year 58 AD. It was intended for his older brother Gallio, to whom Seneca also dedicated his dialogue entitled De Ira (On Anger). It is divided into 28 chapters that present the moral thoughts of Seneca at their most mature. Seneca explains that the pursuit of happiness is the pursuit of reason - reason meant not only using logic, but also understanding the processes of nature.

The first book in the essays of Seneca deals with good and evil. The dialogue is opened by Lucilius complaining with his friend Seneca that adversities and misfortunes can happen to good men too. How can this fit with the goodness connected with the design of providence? Seneca answers according to the Stoic point of view.

In On the Firmness of the Wise Man Seneca argues that Stoicism is not as harsh as it first appears. Recalling the figure of Cato the Younger, Seneca argues that Cato as a wise person suffered neither injury nor insult. Although Serenus objects to this paradox, Seneca provides further analogies to emphasize the impervious nature of the wise person. In chapter 5 Seneca distinguishes between contumelia (insults) and iniuria (injuries).

Seeing self-possession as the key to an existence lived 'in accordance with nature', the Stoic philosophy called for the restraint of animal instincts and the importance of upright ethical ideals and virtuous living. Seneca's writings are a profound, powerfully moving and inspiring declaration of the dignity of the individual mind.

As former tutor and adviser to Emperor Nero, philosopher and statesman Seneca was acutely aware of how short life can be - his own life was cut short when the emperor ordered him to commit suicide (for alleged involvement in a conspiracy). And Seneca proved true to his words - his lifelong avowal to Stoicism enabled him to conduct himself with dignity to the end. During his rich and busy life, Seneca wrote a series of essays that have advised and enriched the lives of generations down to the present day.

Gaius Musonius Rufus was a Roman Stoic philosopher of the first century AD. He has been referred to as the Roman Socrates and is also remembered for being the teacher of Epictetus. He taught philosophy in Rome during the reign of Nero and so was sent into exile in 65 AD, returning to Rome only under Galba. Twenty-one of his lectures survive together with a few fragmentary notes from others, all of which are contained in this narration.

One of the great fears many of us face is that despite all our effort and striving, we will discover at the end that we have wasted our life. In A Guide to the Good Life, William B. Irvine plumbs the wisdom of Stoic philosophy, one of the most popular and successful schools of thought in ancient Rome, and shows how its insight and advice are still remarkably applicable to modern lives.

De Brevitate Vitae (frequently referred to as On the Shortness of Life in English) is a moral essay written by Seneca the Younger, a Roman Stoic philosopher, to his father-in-law Paulinus. The philosopher brings up many Stoic principles on the nature of time, namely that men waste much of it in meaningless pursuits. According to the essay, nature gives man enough time to do what is really important and the individual must allot it properly.
