If you could get daily advice from one ancient philosopher, who would it be?

I'm Yair, I'm a big hiker and thoroughly enjoy philosophy.

While through hiking the Appalachian Trail I was thinking about how cool it would be to actually have conversations with ancient philosophers, and how AI can be used to do so. I mixed in my seemingly life-long struggle of wanting to build better habits and built a habit tracker and integrated a AI philosopher chatbot.

The idea is this: You want to build a new habit or remove a negative one from your life, Marcus AI offers great habit tracking functionality and analytics. Looking for advice? Ask any of 8 philosophers, including Marcus Aurelius, for thoughts and insights about the habit in question, or even general philosophical advice. Marcus AI's philosopher chatbots aren't just conversational, they're operational. Your AI philosopher assistant can check in and create new habits for you, as well as edit your current habits, all with user confirmation. So you can use the AI chatbot as a assistant, or philosophy/habit coach.

With the philosopher chatbot being the core element of the app, the philosophers the you'd speak to are pretty important. Which begs the question:

If you could get daily advice from one ancient philosopher, who would it be?

To answer the question myself I'd say Alan Watts, an all time favorite of mine. (I'd love to add him to the app but I'm hazy on the legality of doing so.)
