It does not matter how rich you are or how poor you are, you have to recognize that lasting happiness is not possible.
When you find a job that is fulfilling, you will feel happy about it.
You get to work every day in eagerness. You hope that you will find lasting happiness in your job.
However, as with all affairs of human beings, just when you find that you are on the top of the world, bad things will happen.
You may lose the job because the company shifts the operations to other country.
A mean boss may take over, and causes life to become a living hell for you.
You may get sick and have to quit from your job.
Lasting happiness is not possible because things change all the time.
We just have to appreciate all the good things that happen to us now, and prepare for the bad things that will come sooner or later.
