The Traffic Light Button

If you have spent some time in Amsterdam (an the same may apply to many other cities of the world), you know the buttons you are meant to push by the traffic light so that it eventually turns green for your direction. There are different types of buttons, but the most common one is a button you press and without receiving any minor light or sound signal, you wait for the traffic light to turn green. Most of the time, waiting seems to long and you press it again. Or just keep pressing it or keep pushing it with a 20*/sec frequency until the light turns green.
In theory, just one push is enough. The problem is, that since you not not receive a signal back, you keep wondering if your "action" will cause any "reaction".
On mornings when its not raining, I find this "button pushing" an interesting metaphor for several moments in our everyday, when you "inject energy" into something, but do not know for a long time, if it's worth it. If your investment (not necessarily monetary) will have its returns, if your efforts are worth it. Interestingly enough, I find it a good tool to help me understand why businesses often think in short terms. Long terms, without immediately knowing if your efforts are worth it can be excruciating. I am an impatient type. Maybe it's an illusion to think that I would think in long term if I was to lead a company.
But I like to entertain this illusion.
