Much Madness is Divinest Sense

Remember that one quote nobody gets quite right?
I'll wait here while you rack your brains for the most profound quote you've ever seen/heard/read, the one with the wording that was kind of difficult to remember, and was also sort of long and complex, but really really relevant to... gosh, well, everything.
Sorry, not that one. This is the one I was referencing:
"Obsession is the word that lazy people use to describe dedication."
What do you think? Agree, disagree? Or, in FacebookSpeak, Like, Dislike?
Here's what I think.
Hm. I could pretend to be really erudite here, cross my legs, rub my invisible jaw-stubble and analyze this statement philosophically until it started to contradict the meaning of life, but since that would be useless, not to mention you might hate me for it and storm my mental talk show with pitchforks, I will simply say that I agree.
That being said, it's not the point of the discussion--ahem, monologue--for today. It is simply a precursor.
The Point of the Discussion:
Listen--read?--very closely. You are about to encounter a series of analogies. Be on your guard. 
I want you to imagine the world and everything in it that you've ever seen or experienced. Imagine the people you've met, the places you've been, the sights you've mentally photographed, all of it.
Now imagine that memory was not real. Imagine that the world was actually just a very large picture; flat and naive, not one pixel more than meets the eye.
Different, no?
That's how I view obsession (please suh, "dedication" is the politer word) as opposed to dabbling. The world is so full of potential hobbies and pastimes and skills that we never quite master most, just experience them in passing, because we realize that there isn't enough cruel Time to take it all in. Nonetheless, if we approach everything like a dabbler, we will only ever have the surface of everything. Isn't it better to leave some things out of the real experience than to have only a picture and no true experience? Wouldn't you rather have a real apple tree than a thousand pictures of an apple?
Or would you trade the sun for the picture above?
If dabbling only gives us the surface of things, we will never reach the substance. In other words, we'll always love cupcakes better than muffins.
(In the slight case you didn't understand the analogy, let me clear up a small point of debatability: muffins are better than cupcakes. They have substance. Cupcakes are fluff. That's why they have to work so hard to be prettier, otherwise they'd never get chosen.)
I'm sure you've heard the expression "jack of all trades, master of none."
I vote this: in order to experience the deepest, the best, the superlative of all, we must truly strive for mastery. We must fling the entirety of ourselves into everything we do with the madness of conviction.

“The only people for me are the mad ones, the ones who are mad to live, mad to talk, mad to be saved, desirous of everything at the same time, the ones who never yawn or say a commonplace thing, but burn, burn, burn, like fabulous yellow roman candles exploding like spiders across the stars and in the middle you see the blue centerlight pop and everybody goes "Awww!” -Jack Kerouac
