These old coins are now worthless.

From now on, I will focus on my studies.

I have been feeling ill for a while now .

Before now , I had never been to the ocean.

I want to live in the here and now.

Now I know how to solve the problem.

Now that you mention it, I do remember seeing her at the party.

Now that I think of it, I should have studied harder for the exam.

Up until now, I have never traveled outside of my country.

Now that I think about it , it was a big turning point for me.
