Whole sector shrinking, should I change fields? - what worked for you?

Our sector has been shrinking and I am unsure if I should wait it out. Any experience at all would help. I have transferable skills but no direct experience elsewhere. Who has switched fields?

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

Thanks for writing this out. I went through something close to it 6 months ago, and it got easier once I kept a simple log of every call and form.
