“We might as well make the most of it.”

You're on a trip with your daughter. You were supposed to return home, but your flight was canceled because of weather. Now you have to stay for another day. You've rescheduled your flight and there's nothing else you can do, so you say:

We might as well make the most of it.

(someone) might as well (do something)

Use "might as well" to talk about doing something that you didn't originally want to, but is now your best choice. In the example above, the speaker wanted to go home. But now she can't so her best choice is to stay and have a good attitude about it.

Here's another example:

A: There's so much work to do!

B: You might as well get used to it. That's how things normally are around here.

Read this lesson for a different explanation of how to use "might as well":

I guess I might as well stick around and have one more.

make the most of (a situation)

When a situation is bad, but you have a good attitude about it and work to make it better, you're "making the most" of the situation.

For example, if you're on a long, boring train trip, you can "make the most of it" by reading a book, taking a nap, or talking with the person next to you.
