Trying to cure part without looking at the whole, could be compared to a chair without a leg and a lamp without a shade. They go together.
Success comes when we’re looking at the whole of something in its entirety, not the half. Half of something means we could end up with a conclusion that won’t necessarily be right.
Stepping back shows us the whole, a full side that gives us the tools to incorporate everything we need to know, so that we can make an informed choice.
