It's not about faith. It's about reality.
Like many others, I'm tempted to go carried away by my enthusiasm and believe in something without much reasoning. Actually I did this in a number of times. It just didn't worked very well for me in the end. Challenging your believes is a good thing. If it has to be about faith, fave faith in your reasoning.
Dude! How about taking some chances with something that already got traction and having some faith in it?
