With nearly universally applicability, this principle is probably one of the most valuable you can apply to your life.
Forming a relationship? Seek first to understand the other person.
Building a business? Seek first to understand the problem and the people you’re solving it for.
Creating art? Seek first to understand your vision and who you’re making it for.
Seeking fulfillment? Seek first to understand yourself.
Regardless of your aim, take the time to understand the essence of it.
