1. I think that you need happiness and money to have a good job. In a way you have to have both, you can't have one or the other. To be happy, you need money.
2. Realistically, I would like to be travelling the world. Whether it be as a tour guide, or because I need to be many different places for a totally random job, I just want to travel.
3. This seems like a good choice for me because I love to travel. I always want to be going somewhere and I never want to stay in the same place for long. I love going for long drives, even if I don't have a destination.
