"I like learning this, but I still like it."

The difference between professional and amateur:

One is work, and the other is hobby.

One is to make money and the other is to spend money.

One is to play before eating, and the other is to play after eating.

One can grasp the essence, the other just stays on the surface.

Some are specialized, some are not,

Knowing that you can specialize,

Knowing that you can't specialize and let it go,

It's called major.

Li Chen

Occupation refers to a person who is constantly improving.

-Takehiko Inoue

It's not my major, but how good the people around me are.

Not because you are incompetent, but because you didn't do it right.
