I think we can all relate to how shaky we were at first on a platforn.....drawing our bows. I can only tell you that it gets better.....and pretty quickly (it did, for me).
Thanks man...I thought it was only me..

One thing you may want to try (and I sincerely hope you'r eusing a harness)......is to cinch your harness up to the point to where it's taut (tight) while you're sitting.I am wearing a harness..but not tight like you suggested..I will follow your advice. That should give you the confidence when you stand.....that even if something bad happened and you lost your footing.....it would probably grab you before you even could fall off the platform.

Peace of mind breeds confidence.
Best advice yet..I know that BUT need to be reminded daily.
Appreciate the feedback..I will follow all of your directions..it makes sense.
