Everyone has options - we constantly define new ones and evaluate their likely outcomes. At work, we quickly learn what options we have and plan accordingly. When you take stock of things as they are, you see the options available to you. But sometimes you realize that the options currently available to you will not take you where you really want to go. This may sound overly philosophical, but it's very sound advice.
Possibility is a great motivator.
If you want things to be different in the workplace, or if you are considering a career change, don't just look at the options you have. Consider the possibilities of the change and go from there. When you stretch your mind out of the limitations of the familiar, you can better see the possibilities open to you. Most, if not all, of our great thinkers and inventors have exactly what Kierkegaard was talking about - the passionate sense of what might be. The good news is that your own technical skills probably contain the raw material to feed dozens of fruitful possibilities.
