Congratulations! Just awesome.
Never look at Pre-flight as routine and boring. You could miss something that may cost you your life.
Keep at it...if you want it bad enough, you will find a way. Maybe you could work there and cut a deal.
If do you get your license, there are clubs that make it much more affordable.
If you don't do it, you will look back one day and wish you had. Because at that time if you followed though, you would be flying now. Who knows where it might lead.
