Focus on What Matters is a collection of 70 letters/essays I wrote about different aspects of life, from happiness, wealth, health to relationships and much more. These letters, inspired by the original works of the Stoic philosopher Seneca, serve as reminders to focus on the right things in our chaotic lives.
