Seneca is a Roman philosopher that was born in 4 AD and died in 65 AD. He's written many works on "Stoicism", or the philosophy of personal ethics. It is a belief structure that is focused on accepting the moments as they are as they come without judgement or aggression against external forces.
Seneca discusses many subjects in his work, but is most noted for his essay "On The Shortness of Life". This work in fact inspired ByMorte, and is the driving force behind our mission to help you grow and appreciate your existence.
The key takeway is to focus on yourself, and take deep appreciation and observation of your own life.
