"sweating like an Ethiopian marathon runner" - that's good stuff! When I started, I walked to every stand, near or far with full camo on, my 5 pairs of gym socks & 3 sweatshirts layered on. Got to stand soaking wet and froze to death.
Here's another one to add after reading above on "busting every doe"....
Walking through food or food plots in AM or even crappy exits at night through food. I avoid it like the plague now and find ways around it. When I started hunting, good gosh was I stupid. Screwed a lot of spots and hunts up. Oh, and ya, when I started hunting, I maybe had 2 or 3 spots.... Just hunted them over and over and over. So funny. I think "Teenage Me" is the worst hunter on this site period!!!
Also..... One I really never did (since when I was younger I really had no blinds or food to hunt over) but I see all the time..... Blinds in the middle of the food plots. It boggles the mind!!! How a guy doesn't get winded constantly during the hunt 1st and 2nd, getting down - has to blow the field every time. Misplaced blinds in general are pretty easy to spot. Go drive along any highway in Iowa - look at the blinds, 75% of em make zero sense and those guys are ruining their spots, blowing fields or not planning for where deer coming & going to. It's funny to look at em. Ideally, I like to have mine on crest of hill with wind in my face of course.... I wanna be able to climb outta that blind with no deer or few deer seeing me. I either have to have my blinds tucked in major cedars or have EW in front of them and then i TRY to position them so I climb down and walk downhill where no deer in food can see me. Ideally.
Few more... Sorry!!....
-Horrid shots because I had my facemask hanging out or even hitting my arm with string because my coat looked like "Stay Puff Marshmellow Man"
-1st year as a kid I sat all day, had pop cans I set on back of my stand to clean up at end of night, stepped on one trying to position for a big buck - ya, he was GONE!
-Getting lost in the woods in dark with new spots and not not having good tacks or ability to find spot. End up angry, pouring sweat and running every deer out of county. Those hunts don't end up well!
-Had the mitten/gloves that "top flipped back" so fingers are out.... Had a GIANT sitting under me at 10 yards.... (like 180"+ Legit) Everytime I started to draw, half way through, trigger on my release would get hit with top of glove.... Took me 4 times to figure this out. Went to grab 5th arrow and take glove off, wasn't there. Buck stood there even though arrows had been sent through trees (windy day) & I watched him for 20 mins.
