Focus on the Root Cause Not the Symptom

I have learned a very valuable lesson from alternative medicine to focus on the root
cause of the problem and not the symptoms.  An example in medicine is treating type 2
diabetes by focusing on the root cause, insulin resistance and not the symptom which is
high blood sugar which will become normal again if the root cause was solved
through diet and exercise. But I can see this idea being applied to any number of 
situations where  instead of being worried about something look for the root cause of 
the problem & what solutions you can come up with.  I 'm starting to do this and find 
it keeps me focused on how to solve the problem instead of worrying about it.  
Oh by the way, don't just look for one right answer but as many as you can find.
