Sometimes you have to be gentle and quiet. Other times you have to know when to get aggressive. That goes for any prey.
Whitetail hunting with a rifle or MZ in thick brush: I have killed deer by bumping them and while they are running their 100 yards before stopping to look back, I've charged forward to where I know I'll have an unobstructed shot. In that situation, you're already busted and they can't hear you moving because they are running too.
This year elk hunting, there were a few times when I waited to see what would happen and it cost me multiple shot opportunities on a nice bull.
Too often it's easy to be passive when things are happening and it's tough to make a decision to be aggressive.
If your seeing fresh sign, but no deer your moving to fast.
Or you're in a nocturnal area (depends on terrain and species)
Elk will sometimes stop running after 100-200 yards in thick cover.

especially when playing cat and mouse with a bull w/ cows. Talk about frustrating!
