> The person who wants to spend all day building robots to feed the poor, and the person who wants to spend all day writing are probably not going to both be happy in the same job People don't actually work that way though. My favourite sport is rugby union, my second favourite sport is swimming. These sports are very different and yet I am passionate about them both. Rugby league and American football don't interest me at all despite being much closer to my favourite sport than swimming.
