There is tremendous value in determination. Focus is a virtue. As with all things, too much of a good thing can be harmful. If you are intentionally unaware of your surroundings, you can miss out on opportunities to react to the marketplace.
No matter what our best intentions, no matter how well conceived our strategy is, things don't always go the way you hope or intend. That's the way of the marketplace. Do you keep grinding on an initiative that does not add value to your experience or your business? The answer is no. The wisdom that comes with experience lies in knowing when to pull the plug on certain initiatives, and when to stick. This is an art more than a science.
For this, a change in perspective is almost always beneficial. For example, I recently went on a walking tour through a town that I have driven through many times for years. While in the car, your attention is consumed with driving safely. Maybe you are on the phone, maybe you are preoccupied with the meeting that you are going to. Your world, for the most part, is limited to the space inside your vehicle.
When you walk the same route, however, you are presented with a totally different reality. The attention that you had to divert to driving now can be used to experience your surroundings and notice the buildings, the architecture, the alleys, the trees. All your senses can be engaged and the sounds and smells of those neighborhoods reveal themselves. The experience becomes much more visceral.
The ride in the car is not the walk on the street.
Taking yourself out of your normal perspective allows you to reevaluate your surroundings. You may make different judgments about what you sense and how those things impact you.
When you realize that something in your professional life doesn't add as much value (or any value) as you thought it once did, then make a move in a different and more productive direction to get to your objective.
Check and adjust.
