What I can say is, the first money i ever earned, aged 15, went straight into a state of the art sony digital camera. I thought it would really compliment the fact that I was heading to Spain for an exchange year and would like to capture some of that. From then I kind of looked at photography as a self-evident asset to traveling. Now, 8 years later, I still travel a lot. The difference is, that im actually starting to really like my work. Maybe due to the better camera I got now, or the experience, or whatever... but if I hadnt spent my cash on lenses, I'd definitivley make my flat a gallery... :D
