I accompagnied my wife to the barber's recently. The cutting looks so easy, everybody should be able to that! (Just like software.) I kept looking and learned. Even though it looks like he is just cutting away, he doesn't. There are different movements for the different stages, and there are tricks to check if the (long) hair has the same length on both sides.
Learned: To make it look easy you need to know what you are doing and what you can do. The last part, your options, are the hard part. You can't just bash away (at the scissors or at the keyboard), you need the confidence that you can handle upcoming difficulties.
