How are we supposed to know if we’re happy? I like this definition from the Stoic philosopher Seneca: "Happiness is having a clear sense of the path that you are on, not being distracted by the paths that crisscross yours. Especially the footprints of those that are hopelessly lost.” If you know where you’re going, if you have a sense of direction in your life, you can just go on your way. Sure, some people will be faster than you. Others might be taking off ramps that you might wonder about. But if you have a clear sense of the path that you are on, then you understand that someone else’s path isn’t for you. You’re happier to go in the direction that you set out to go in. That’s the tranquility, happiness, and peace that I want right there.
