Why You Shouldn't be a Jack-of-All-Trades

BE A MASTER AT ONE THING, THEN BECOME MASTERFUL AT EVERYTHING ELSE

Don't Try to Be Well-Rounded Before Any Skills Have Been Obtained
Many people try to become "well-rounded," which is an admirable desire, but they often pursue this lofty goal while they still have 4 metaphorical square corners as their skill set.  In other words, they have not become exceptional - a master - at anything yet.

Observation Knows Best
From observation - and nothing else - it has become clear to me that persons who attempt to really master one skill attain two huge advantages over those simultaneously trying to master numerous skill sets:

1. They are in a select group of people who are masters at their thing and thus are in much higher demand.  Thereby, success is more likely be obtained.
2. They have learned what behaviors, processes, and effort is needed to become a master, and thus becoming masterful at many things will take far less effort.  To me, this is the magical blueprint.

Cautionary Note
I must make a note for those who read this and think I am suggesting not to attempt to learn multiple things at once - akin to multiple classes in formal schooling.  I applaud those who desire to be a polymath, but what I am encouraging is not trying to master all things at once before you have learned proper behaviors and processes that have truly taught your mind to think.  

Therefore, be a master at one thing, then become masterful at everything else.
