Getting to the top

So, I was thinking about people and how smart they can be and how each person decides his own destiny and all that sort of related gibberish. Everyone does this some time or the other.

I was thinking, hmm, everyone is born with some inner latent ability/talent. Some persons are just smart, and some are just dumb, but most are in between! This is obviously demonstrated by a normal curve! Let's call this the inner ability everybody has the Latent Factor(L). 

Also, not only does it matter that a person has a high L, it also matters how much effort they put into their lives. Let's call this the Effort Factor(E). As a sweeping generalization(a logical fallacy I agree), we'll assume that this variable also has normal distribution. 

So from these two variables, a person's Quality Product(Q), or how good a person is in general at something is given by

Q = E x L

Now, L is generally a constant, but E isn't.   An overall distribution for a population would would like this...(spare the inaccuracies, please)

But the thing is, the top percent on the L graph don't have to be top 10% in the E graph. Or just put, someone with an L of 0.5, the worldwide average, can easily have as much Q as someone with a high L(say,1), simply because of the fact that most people have a Q of around 1/2!!  Of course, now the question becomes, how hard is it to get a high E, to sufficiently bump up your Quality Product to super-average levels? Just work hard I guess!
