So obvious, it’s often overlooked. Page 126 of SHIFTING Into 4WD offers this:

I have this bucket of red paint. I paint the fence. Oops, I wanted blue! Let’s do it again. I grab the same bucket and paint away. Darn, it’s still red. Several redos later and the fence is still red. How come?

You gotta change something to change something. If you think that’s too simple to mention, you should see what I repeatedly see. Same hill, same track, same speed, same gear, same T-case range, same tire pressure . . . same disappointing failure! You’ll get the same results if you repeat the same techniques. This is as true for life as it is for driving.

As I’ve preached before, I recommend a crawl before you walk before you run 4WD learning process. That does not always make for successful first attempts, but that’s OK. However, if your second and third attempts are identical to the first, you’re stuck in crawl. When you don’t get what you want, on the trail or in life, change something! Knowing what to change and how much comes with time and practice.
