Welcome to the world of Bowhunting! First and foremost don't get frustrated. Its easy to do, but like you said yourself its easy to make dumb mistakes, and guess what that only leads to MORE frustration. Next take into consideration this is your first year in the area, so use it to help learn the area the best you can. Try multiple stands throughout, not multiple tree's within a spot. Over use of an area will key deer onto you very quickly if this is what your doing. Next, humm only your 3rd year with the arrows. Took me 7 yrs also to stick my first, and I only had 1 shot in those first 7yrs. Finally if you can take a good doe, what are you waiting for. Its meat in the freezer, and it only boosts your confidence. Oh 1 more thing, enjoy the time and experience. Its really what its all about. Good Luck!
