I agree! But you won't do it forever, sooner or later you realize that you've worked in something you're not passionate about. It will result in serious consequences.

More important than passion and effort is long-term goals. I believe to be successful you must project yourself in the future. Look what you will be if you continue to walk the current path or what you will be if you change your path. The key is to choose the path that will bring you to a brighter future and stay in that path in turbulent times.

Choosing the right path is not as easy as speaking but an everyday exercice.
