Personally, its not all about work and money - Here's some insight into my passions and how to foster yours too.

You definitely have to have some sort of passion or hobby outside of work and business.

I am a true believer in that people will go crazy if they don't find something to pull them away from the everyday stress of professionalism. Even though you have a career, doesn't mean you have to end everything else in you life that matters to you.
Lucky for me, I am still able to fully engulf myself into my passion for music.

I was a DJ before I started my real professional career, and I can still proudly label myself a DJ now. I have even had the luck of meeting others who engage in my passion, and we have developed a group of DJ's that work together. You can basically call us a full entertainment service company now.

My professional career requires me to be in my office by 6am everyday, and it is pretty much a fast paced grind until 2pm. I leave the office at about 3 pm and arrive at my place of dwelling where I'm greeted by my room of passion (My DJ Studio Room). There is nothing in my room that would indicate that I am a corporate professional. It is basically my version of Disneyland.

That said, I feel that it is of great importance that you incorporate your passion into your life frequently. The world needs more sane people, so do your part and enjoy yourself when not handcuffed to the demands of your professional career.
