The difference between professional and amateur

May I ask, what is the core difference between a professional and an amateur? It's not just the level, but also the way of doing things.

　　When an amateur sees a problem, he often solves it by instinct, by intuition, by working hard on the problem itself.

　　A professional, on the other hand, because he knows the system well, knows that the most obvious solution, but will make things worse. So he will try to change the interaction between the elements of the system and the elements.

　　The simplest example is: a big dog bear sees a door closed, he will just go to the door, because it is the most obvious solution; but a person sees a door closed, he will go to find the key.

　　An amateur runner, can not run fast, he will run desperately. A professional athlete, to improve speed, he will do targeted training on different parts of the body.

　　So there is a good saying: "If you lose your key, then it is basically certain that it is not next to the lock." That's what it means.

　　Amateurs see isolated events, while professionals see the system behind the events.

　　The little hook of trust

　　We have a sign in the bathroom at work that says "Sanitized Today" with the date of the day underneath, for example, May 10, 2019.

　　Obviously, this is to manage the cleaning staff and make them do their job every day. I guess you've seen similar signs in many bathrooms.

　　One day, I asked our colleague who is an administrator why we hang it.

　　Every day, the cleaning staff only need to erase the last number on the date, for example, tomorrow only need to change May 10 to May 11 on the line ah, he can still be lazy not to work.

　　Colleagues say, this is human nature ah. After all, he has to come every day to change a number, if not this little constraint, he really may be lazy.

　　And with this small restraint, the probability is that we have to believe that he will do his duty.

　　Just like you sign your name on a pledge, not only has the force of law, but this signature itself is binding.

　　Binding a person, in fact, often requires only a small hook, the rest is left to trust.
