I am to do my homework tonight.

Practicing what you learn is one of the most important "do's".

I enjoy doing various activities in my free time.

I love doing do-it-yourself projects on the weekends.

I prefer to do it myself rather than asking for help.

I feel like I'm always doing nothing but doing chores.

You would do well to tell it to him in advance.

How do you do?

If you want to succeed, you need to work hard and do so consistently.
