I think design is such a powerful discipline because it’s fundamentally not about you. At its core, you are building something for a user. Thus you need to understand that user on a deep level.
Same with entrepreneurship. You need to know your customer, their tendencies, their hopes and desires. It’s not about you.
The practice of understanding that it isn’t about you is powerful. It opens up doors. It forces you to empathize. It changes the world.
