but it's really hard not to let others' doubts and declarations of "Oh that NEVER works" get to me.
Best response to this, "Oh? And how many times have you tried it and had it fail?" Then you will either learn some "deep, dark secret" of theirs, or they'll just say, "I'd never do that!" or some such. Which also has a simple reply, "Well don't knock it 'til you've tried it." and just keep on going remembering that some people will keep on saying that something is not possible while we are in the middle of doing it. (isn't that someone's siggy quote on here?)
