I don’t really think about that much when I’m working with people in our department on laser engraving, because I think it’s a big case for our company, and I’m sure I’m going to do my best, but I’m sure I’m going to be very upset if I have some difficult problems in the process of developing laser engraving. Happy, my superior told me that if you don’t even have this ability to resist stress, you are not suitable for the development of laser engraving, I think my superior said is very right, because I am the kind of person who has no psychological endurance, so if there is any difficulty, or to self-regulation is better, so Maybe there will be better results.
