(something) would (be something / do something)
Say that something "would be ___" to describe an imaginary situation.
If I were rich, I would travel around the world non-stop.
In this example, the speaker is imagining having a lot of money, which isn't really the case.
Here's another example:
Don't you think that you would get tired of talking with fans if you were a celebrity?
You can also use "would" to talk about something that might happen in the future, but isn't certain yet.
If you sold your business, what would you do for work?
If you went to Spain, where would you go?
