How can ancient philosophy help us with today's worries and stresses?

This book explores just that.

The ancient Stoics were deeply concerned with the virtue of equanimity. Equanimity or ‘inner peace’ is a prerequisite for being a happy and flourishing person according to Stoic philosophy. Therefore, it’s no surprise that ancient Stoic texts contain invaluable wisdom on how to calm the mind. The challenge, however, is to find and translate this wisdom in a way that’s simple and comprehensible in our modern context, while still maintaining its profundity.
