Now, in front of me, I have two jobs.

(1) Drafting the development completion report, and (2) Constructing the Docker environment.

Obviously, from the view of urgency, importance, (1) is a priority.

Also, considering the required work time and work cost, (1) is cheaper.

Furthermore, you should definitely start with (1) in light of the comparison of whether it is an essential task or optional self-development.

However, let people stand out.

Even so, there are a person who will start (2) Constructing the Docker environment.

Remember that it is a creature that is called "engineer".
