I will give a few that I think of every year:
1. Believing that you will get winter weather and the rut will be on in CO 3rd season.
2. The amount of points it takes to draw a unit directly corresponds with quality
3. If you are hearing a mule deer unit is hot, it's too late
4. Believing that Nevada has the best system for tag allocation because you get 5 choices, everyone gets 5 choices
5. Setting your goals on a 190 buck or 370 bull just because it took 10 years to draw
6. Failing to monitor drought and moisture levels as it is way more important in trophy quality then how hard the tag was to acquire.
7. Realizing a once in a lifetime hunt isn't the same if you don't have your buddies or family there to share in the moment
8. Failing to monitor the unit that you drew once and are hunting again several years later and expecting the exact same hunt
9. Your preference point portfolio is absolutely meaningless without a plan and understanding that the game may change and you may be left with nothing but regret
10. Continuing to put off hunts until the conditions are perfect, while losing your physical ability to age
