CMD ["localhost"]

Repetition without real progress

… it becomes bad when you continue learning even when you know enough. Even when you’re capable of jumping right into the project and figure things along the way, you keep delaying it. Beginning something new is uncomfortable, therefore instead you choose to read an article or take a course just so you can tell yourself that you’re working, but in reality, you’re just looping, you’re not making any progress on the project.

Repetition (in learning the same topic) can give a false sense of achievement. Of course I will get better repetition after repetition, but that is diminishing return. It is dangerous to indulge in that warm fuzzy feel-good feeling, while the whole time I am just re-learning the same elementary concepts.
