I often try to come up with ideas....something that will make me a more efficient/effective hunter, something that could possible make lots of $$$ so I could sit all day-everyday!!

This often gets me through the day....and just the fact that I'm not working is often enough.
The other tip for sitting all day would be to sit in an "all day" spot. I'm not sure I could sit all day in an area that I did not think could have the possibility of all day movement. I have sit in places allday knowing that the only movement would be the last hour of light and that makes for a loooonnnnggggg day. I've only done it a couple of times during early season when I was on a good buck that I thought was bedding too close to the food for daylight access.
Sitting all day is one of my favorite things to do....and I see as much movement from 11-2 as I do at dawn and dusk.
