passion

whenever i see someone who is really passionate about something...i always think how nice if i m so passionate about something...my professor told me yesterday that he is really into photography, an interest which started since he was a teenager some 50 years ago...the other day another friend told me that reading the history of her ethnic group makes her want to write like that in future, so that she can document the history of her ethnic group...this made me think about what i m passionate about...used to be very passionate about reading, songs and sports...i am still very passionate about songs actually but i wonder, will i still be just as passionate 30 years from now???
