"What you learn about yourself is that you continue to see that you're selfish. It's so easy, in our Laodicean culture with all the different things that grab our minds that aren't of eternal value, to let those tentacles wrap themselves around your heart. That's one of the reasons why we love going overseas. It helps us to break free of those things. We've been on all of these trips, but it's easy to slide back into the selfishness of life. That's what we find out about ourselves."
