Adding to what @MISkier is saying - a lot of times I hear/read "don't do that", "do this" with no explanation as to why you should be doing that, or how to do that.
For example for getting better stack/alignment, it's no good telling someone their hips are behind them and to get them forward. The how is focusing on one of a straighter back leg, squeezing glutes/core, or tensing legs. That's what builds the muscle memory.
