So true, pretending to know what you don't know is not good. Better ask than to create mistakes

In my own expirienced i always asked when i'm interested to learn on something but i observed at the same time. As a dental tech. we are more on skills, that is why the best thing for us to learn is asking those who are superior to us if we don't know the procedure. Because when we start wrong then we will end up to failure, but when we start right then we will end up to success!
