Oh yes. There was this fantastic seminar in Florida a few years back, and I was in CA living check to check with no means of buying a ticket. I broke it down into three pieces - the time, the money and the ticket. The ticket came from a friend with a frequent flyer ticket. I was tutoring her husband, and being broke too, they didn't know how else to pay me. Worked out well.
The time part was that my boss agreed to switch days off so I could work a 6 day week one week and a four day week another, giving me the time I needed for my connections.
The money came when my bank offered me a higher line of credit, which was the $400 I needed to pay for the course.
As I recall the weather flying in and out was hair raising, but it was such an inspiration - and I am so glad I went. Going through a similar experience right now - next weekend to Budimpešta. The story will probably end up becoming a soon to be published Hub!
