Some people treat you so badly and think that's OK as long as they give you a few dollars. 2. Many people are suspicious of us but I believe those people are the ones with something to hide. 3. It's true that I have had to put my hands into and look into some nasty places, but the money's great and everybody wants to know one of us! 4. It's not all fancy performances and globetrotting I can tell you! Without hard work, dedication and lots and lots of practice, you won't succeed. 5. We have become a lot more aware in recent years about health dangers that exist while working here and now we are even more careful. After all, I want to remain on this side of the curtain! 6. It's great seeing paper plans come to real stone and brick reality. 7. We get paid a lot but there's always the risk of injury and our careers are pretty short. 8. The first and last five minutes are the most stressful and that goes for the members of the public as well. 9. Some days, I get blocked really badly and can't string more than two words together. 10. In this institution, a lot of it is control. When you consider their home life, that's understandable! 11. I consider myself an artist, I really do! What I create lasts a long time and can even change throughout the year.
