Attention to details
Recently, I got an opportunity to watch a skilled laborer work on a temple. Now, this is just a little temple for an apartment complex. Only when I was watching him work, did I realize that all of the intricate work is done free-hand! He was working with skill and patience, and literally carving the wet cement to create the patterns.
Notice the real nice, intricate patters. Yep, free-hand! Beautiful, eh?
I overheard this man talking with another one in his clan about having passports and needing to fly. Quite clearly, these skilled laborers have opportunities abroad.
