Ask your grandparents this question and they'll laugh in your face. Passion-for-the-masses is a 21st century invention. Just live your life, do what you want, when you want. Do not worry about having a so-called passion no more than you should worry about not having a unicorn as a pet.

I think a more valid question is how someone can focus something for 30 years while most people cannot do that. This definitely cannot be explained by IQ, initial curiosity and others. Some people can tolerate this perseverance but others cannot.
