"Jacks and Jills"

 "Jacks and Jills of a few trades, Masters of NONE"

lampooned here as,

Or... "Jagoffs of opinion-trading, Masters of NOTHING worth knowing!" 

Or... "From Vomiting every opinion that comes to mind, to 

Understanding and keeping your mouth shut."

There is, of course, at least two takes on that, more famous, idiom: 

• the easy and obvious one, having to do with "doing things" in the external world, like fixing toasters and other small appliances; 
• the not-so-easy and non-obvious one, having to think about "thinking things" in the internal world, like "Inquiring into 'Reality' and 'Enlightenment'" and other strange ideas.

Regarding the non-obvious one (for those who didn't take the subtle challenge embedded in all of these postings... i.e., always think faster than you READ, and see if you can "GET IT" before the punchline comes) most people are not only Jacks (or Jills), they are quite content to be so, if not "proud like peacock,"

whereas too few on this planet are Masters, 

and they wouldn't settle for anything less.

Jacks and Jills remain that way (settling for LESS) because they don't how to "specialize", which often means to direct their focus and attention for long periods of time, over hours, days, years sometimes. It's simply a lack of will power, right effort, and most importantly knowledge.

Masters are not born, they are self-made by desire, passion, directed attention, focus, and trying to see into and beyond the depths of something, rather than just settling for the ordinary opinions so prevalent in this world.

Mere opinions about every-damn-thing... 

versus 

Understanding about EVERYthing.

or...

Jacks and Jills of nonsense and silliness...

versus 

Masters of ALL and EVERYthing.

Which one are you?
