Happiness is the most elusive of human feelings.
How many are happy with their life? Happiness depends upon fate or upon the choices we make everyday?

Love it, change it or leave it:

If you don’t love what you are doing than choose to change it: if you don’t love your life than choose to change it. Change always leads to new roads, new stories, new lives.

If the change does not lead to anything good then continue to choose and choose to change completely the road. A situation that will not change despite your will than cannot be changed: better to close that chapter of your life once and for all to start a new one.
