Okay.

[then this is why you need more practice; but Linneus isn't going to say "I told you so".]

You need to backtrack. Before you were securing your hands first then moving your feet; this time you want to secure your feet first and then move your hands. Hold onto the bough first to get your footing settled. You aren't far up- [translation: you haven't far to fall] -so you can always jump down some of the way.
