VERY true. The first time I did a perfect breakfall was because I was put there. No fear, no pressure, just....there....
Which reminds me of a vicious circle that can happen with ukemi. Nage throws me in a way that doesn't require a breakfall, so I don't breakfall. This causes nage to conclude (incorrectly) that I *can't* breakfall. Which causes nage to throw me as if he's afraid I'll break. And so my ukemi looks tentative because I'm not sure where nage is trying to send me. Which makes nage's throws even more tentative... Sigh...
