Over-thinking is a rabbit hole. As humans, we have a tendency to spend too much time in up our own heads and paying attention to our own wayward thoughts, which, ultimately, just spins us around in circles. Action is the best circuit-breaker for this. When we take action on our ideas or goals, we drag our thoughts and feelings along for the ride. And that ride takes them to a healthier and more productive destination.
