The other side is always green - this a a big myth
There are people in this world who think that there is something better on the other side of the fence. This never happens, and in most cases, it is not true at all.For example, there is a tendency to simply quit a particular organization, just because the boss is a horrible character. The person soon realizes that the boss in the new organization is even worse than the previous boss!! The wisest thing to do is to pick up a new skill set and then join another organization where this skill set can be put to best use. For example, an HR middle manager acquired a Diploma in Psychometric testing and went on to practice this well in the new organization. He soon became an expert in the field and enjoyed his job at all times.
The other side can be green, provided we plan for it. It is not always true, as a matter of course.
