Whole sector shrinking, should I change fields?

Our sector has been shrinking and I am unsure if I should wait it out. I have read a lot of threads here and could not find my exact situation. I am open to a pay cut if the field is stable. Who has switched fields?

Talk to people in the field you are considering. Two coffee chats changed my mind about one option.

Keep everything in writing and save the confirmation numbers. It made the follow-up calls so much easier.
