Muscles are a lot like life

Saw this at the gym the other day and thought it was a good analogy:

"You can’t change the muscle without fatigue, and it’s impossible to really fatigue the muscle without pushing it. The only way it gets transformed is by pushing it beyond what’s comfortable.

It’s kind of like life. Our lives don’t really change until those moments where we were pushed, and that’s where we grow the most and our life becomes more rich. If you don’t push your body beyond what it’s comfortable with, nothing changes."
