Here's a good video of Robert Greene talking about one of his rules "Assume Formlessness," from his book "The 48 Laws of Power."
Just like Bruce Lee said "Be water my friend," this can apply to your lives by being adaptable to whatever challenges you face. I'm a very structured person and prefer to stick to a schedule and create lists to stay on top of things, but sometimes something happens in the day that derails all of my plans. Opposed to be thrown off by this event, this advice tells me to go with the flow or "be water" and adapt to what is happening. Sometimes I may freak out and become discouraged that my schedule for the day didn't go according to plan, but this is the importance of following this advice so I stop freaking out and be in control of my feelings.
Have you ever applied this concept in your life? If so, comment below and share your story, I'd love to hear about it!
