I love the positive attitude! That's what it takes to be successful. Confidence is such a critical part of bow hunting. Stay confident my friend! Don't give up, continue to push yourself.
I like your willingness to try new things...hopefully that will develop into a desire to try new adventures. Treestands are not always possible in extreme environments. Learning to spot and stalk from the ground, now, will put you in a better position for success later. I can always tell when an eastern hunter comes west. They always flounder when the hunt hits the ground and the game does not follow a set pattern.
HAVE FUN! Don't let anyone tell you. "You can't!"
