RE: What's your weakness?
Something I worked on this year was staying still on stand. I fidget and think it costs me without me knowing it. The other thing I'm working on is being quiet getting in and out of the stand. I hunt from a climber a lot so setting up requires some noise, but I want to minimize it as much as possible.
Another weakness is farting on stand, seriously. I have IBS (irritable bowel syndrome) so for me not farting is not an option. It's hard to shoot a bow when you're doubled over with cramps. So, playing the wind is EXTREMELY important.
