Diversify my hunting locations.
Spent way too much time within 200 yards of food plot that actually grew stuff. My one stand not in that area is in a dead tree, so I was too chicken to climb it, and too lazy to move it.
For all practical purposes i was hunting about 25% of the actual property.

Scout in 2 weeks. Scout again in March looking for sheds. Mark things down on the map. Put stands in places. Hunt those places. and move.

DON'T OVERHUNT. I absolutely killed that same ~200 yards from The start of gun season until Middle of January when I started thinking about why I hadn't seen anything.

Always look for new spots and use my climber more.

Hunt longer per sit.

Shoot older deer.

shoot more deer.
