What is your passion? And why?

If you have more than one passion, try and pick the one you are... Most passionate about!
If you can't, then go for it, explain why you have more than one.

• What is your passion? If it's something obscure tell us about it!
• How did you end up with that passion? What was the inspiration?
• How long has it been your passion?
• How do you practice or express it?
• Sell it to someone reading, why is your passion so great to you?
