Afraid to fail

You know those little square cards that have the great quotes? I LOVE those...they are just cheesy enough for me. I saw this one yesterday and like it...it made me think which is always a good thing (at least I think so).

"What would you attempt to do if you knew you could not fail?"

I think there are a lot of things I would do if the risk for failure wasn't out there...I would go all out on my diet again, run a marathon, go to medical school (if I could get in ever), have tons of kids... But really, how much does the threat of failure keep you from doing the things that you dream to do? I think it plays a factor for me and maybe it shouldn't. I wish I could give all of me to something and not always have in the back of my mind the thought that it might not work out. Hmmm...me thinky too much.
