Patience is very important when you are learning archery. There will be days when you shoot is going to be terrible, and other days when you are going to be shooting great. This is a normal process because your body and your mind are both adapting to the changes. Don’t let any of this get in your way and you will achieve excellent results.
I remember that I felt very frustrated at times and I would make a real effort to focus on the basics during those times. This would help me tons and I would see an improvement after doing this. Your practice should be consistent and daily if possible, but if you feel frustrated and unable to get results, it might be a good idea to get back to the basics.
A good Stance, Posture, Anchor, and Release. As long with more ‘Blind Bail’ shooting and breath control. Slowing things down and enjoying the process.
