One of the simplest and most profound lines I've ever read was the title of a book. It said, "Don't Stop at Green Lights." This has been a major theme of my life. My regrets have mostly not been my mistakes in action. My greatest regrets have been an opportunity I didn't appreciate or recognize or one I saw the value of and was too hesitant to act.

I've come to realize that in making a decision to act, I'm able to be surprised by resources or support for moving forward that I didn't see or expect arriving until I was in action. This has been one of my most important lessons. We think before taking on a challenge that we don't know how to do it, or we don't have what it takes, or enough to work with. So we don't give it or ourselves a chance. We don't ask for help. We don't improvise. We don't look at the upside.
We only look at what we can lose. Or we exagerate our risk of loss, or how much we think we can lose...and ignore what we can gain, or underestimate our rewards. We don't give enough attention to the upside, especially the adventure, the fun, the excitement, the learning.

So, when opportunity presents itself, don't stop at green lights.
