Here is my take on this.

As far as luck - throw it out of the equation..why..because though there have been hunts where I felt I got a little lucky, there have been just as many where I have felt that old lady luck was looking the other day. So for every time i did get lucky there are just as many, if not more times I felt I was unlucky - its a wash

As far as land - you do with what you have and judge your succes accordingly. A trophy hunter in Florida is not going to hold out for a 170 but a hunter in ILL. might. That 130" in Florida is just as much an accomplishment in Florida as a 170 is in Ill. - just a rough example. I have done all my hunting in high pressure public land, and have leaerned NEVER to blame my lack of success on the woods I hunt. Where there is a will there is a way. The deer, even the big deer are there, if you hunt this type of land, and you want those good deer you just have to work harder than everyone else. That brings me to last and most important factor...

Skill - or a better term I think is work. I made up my mind many years ago that I will eat my last buck tag stew, and that i would give myself the best oppertunity that I could to put myself over good bucks. There is a real, and just reason that some hunters around me were consistantly killing much better and more deer than me. And it was easy to say " yea but that guy hunts some great land" . Well that may be true, but upon investigation he was also scouting and working at his hunting 500% more than I was. My eyes were opened to what it takes to kill good deer in my area, it takes more than a month or two of fall scouting and a handfull of stands, It takes more than putting the bow away in december and concentrating 100% on fishing until september. It may come easier to some, but for me to consistantly kill the deer I want to kill, I have to have horns on my mind 365 days a year. I have to scout and create options all winter and summer long, and this mind set has enriched my experiance ten fold.

My opinion is take every other factor and throw it out the window, if you are willing to put in the work (some areas require more than others), All the other things that seem so important just fall into place.

The good hunters never rely on luck, they expect it
