Want to think like a designer

I saw this headline today

"Want to think like a designer? Try these 4 simple exercises
Even simple drawing exercises can get your creative juices flowing."

Why is it that thinking like a designer seems to be so easy to do and to learn. We do not very often see headlines like

"Want to think like a heart surgeon? Try these 4 simple exercises
Even simple cutting exercises can get your surgical skills flowing."

Of course, there is a difference. We cannot train as surgeons by cutting in people, but all of us can make drawings without any dangerous outcomes. But that does not necessarily make us good designers or help us think like designers. To do good design is difficult. It requires a lot of knowledge and expertise and experience.
