I think you still classify opening up shop as a great achievement!
Mine? Hmmm... well, it could be that 100,000 visitors in a month on AardvarkTravel.net thing but I won't mention that - ooopsss... too late. To be honest, I have absolutely no idea. Maybe my greatest achievement is simply running a business even though I'm orange, have a big snout and am just 4ft tall.
