1. cooking - to make nice retouching good taste is needed
2. hairstyling - sometimes you have cut
3. sewing - sometimes you have to paste
4. cosmetology - when you retouch acne in face in the portrait
5. gardening- for nice colors composition
6. police training - to catch right software, interrogate, to keep it after or let it go if not important
7. computer programing - you have to know heart of your computer to make it beats right for you
8. sleeping - after 10 hours of R&R you are sleeping even if eyes are open
9. brain surgery - this is precision you need for work you do and for way you eat japanese food upon a keyboard
10. learning Japanese it's exactly what you do after , you're looking at empty sushi box and while you are waiting for a sign from heaven you read jookimiiiizuuurrriiiii kimmmoooooniii
11. rocket science come after you read nice work contract
12. and at the end comes coin colecting
