I think as working actors, it's like sales. You're only as good as your last sale, so you put your all into something and you just hope that from that you can get your next job.
What a pure blessing it was to have a bath in a tub alone in a room where all you had to do was pump the water, not tote buckets. Then all you had to do was pull out the cork, not tote more buckets to the back porch--that kind of thing is easy to take lightly until you don't have it.
