When I first became a physical therapist I used to constantly think, "I could've come up with that." I'd pick up The Stick, the BOSU ball, and so many other pieces of equipment and wonder how it became so widespread.
I've never actually wanted to create a piece of equipment, but I've always had the desire to leave my mark on physical therapy.
I spent the first few years of my career trying to figure out "my thing." I wanted to be an expert in something, I wanted to uncover something new, and I wanted to leave the profession better than when I came into it.
I'll give you a hint... it doesn't come down to a single "ah-ha" moment.
