One thing to consider - hunting hard all day every day for many days in a row is an unsustainable endeavor for almost everyone. I have the best success when I'm hunting no more than 2/3 of legal light, especially if the hunt is longer than 2 days. Building in breaks, taking time to rest, relax, take in the scenery, and eat well goes a long way to make my actual hunting time more focused and effective. In other words, keep my head in the game, avoid becoming overly fatigued, and reaching the point of no return when I just want to quit and hang it up.
