Happiness, a choice or not.

It does not matter whether you're a doctor or a journalist, a lawyer or a banker or even a president. The most important thing is that you must do only that which has your heart in it.

If you love what you do, then your work becomes easier.

Look at footballers and musicians, the first thing you notice when you watch them is that they enjoy what they're doing.

When you have passion for what you do, the passion would drive you to success in your work.

It's important also that whatever you do, you should strive to be one of the best in it, if not the absolute best. Even if you're a plumber, let it be said that anybody is looking for a very good plumber should come to you.
