your never too old to learn new things, especially a new sport! my advice is to hang around this site because there truely are alot of great people here to advise you and are always willing to help beginners. like the others said, practice all you can and get to the point where your confidence will begin to grow and in turn you will not worry so much and second guess your skills.

dont feel afraid to ask any questions about hunting that you may have either, were all here to help other hunters. again, welcome to the addiction!
