For those, who don't like calculating and equations, lets go with another analogy...
We know that if you drop a marble on slope, it goes in the direction of slope and settles at bottom, such that it can't go further down, without climbing something. (In maths, term is "local minima")
Say, there is this surface, like earth, with lot of mountains and ditches. If I drop a marble, it'll go to a ditch. Now, consider height as opposite of your satisfaction level. and gravity being your motivation. You want to go down.. Simple?
If laws follow well, you'll do what gives you most satisfaction.
But.. and here comes the inertia part.... Say, surface is made of a cloth and marble has weight.. what happens. Even on flat surface, marble puts weight on cloth, creates a ditch for itself and settles itself. Even if it is lying on top of a mountain, it'll think that it's in a ditch.. and hence don't want to travel anywhere.. and surprise... it doesn't go down....
Similarly, due to the K' discussed in earlier post, or our hatred to do stuff, or stay in inertia, although there is a slope made for us, we won't do it.... Easy, right... In other words, if I sleep even till 11 AM, I should be excused.. and its law of nature I am following (:P)
Super analogy :)
