For me personally, hunting deer on the ground with a bow is the ultimate challenge. I can go out almost any night in the early season and sit in a tree stand and arrow a doe or small buck.
I'm not really interested in big antlers, so for me the challenge became getting close to them on their own terms and on their own turf.
I've been lucky and have taken several deer from the ground with a bow. It's a rush every time and has made me a better hunter I believe.
For some people, chasing big bucks might be the challenge they need to keep it interesting. Some people like to target and pattern a specific deer throughout the season.
You have to find ways to challenge yourself and to make yourself a better hunter.
Nothing against your skills, cause I have no idea what skill level you are. But for most people, two years in the woods is not allot of time, and certainly not enough time to have mastered too much of anything.
Just keep chasing them and try to learn some thing new every time you go out
