Most of what I know about hunting its been learned through trial and error. Errors will occur whether you want them to or not. Mistakes are difficult to avoid, especially in hunting.
Hunters mistakenly believe the way to avoid making mistakes is to avoid trying new tactics. I think we should try new tactics.
The truth is that what you been doing is going to get you what you been getting. If you want changes in your success rate, you must first change yourself.
