gap bewteen what one preaches and what one practises

i am pissed off with this one... and am sure there are many others like me...
but what i am not sure is: which number is more -- the ones who prefer a gap (and willingly keep it) and those who struggle every inch to weed out the gap...
but i have a hunch that the former outweigh the latter since it is always easier to keep a gap, and move on...
it is a who-cares? attitude, a thick skin, an attitude of convenience that permeates most...and let me add here, it is to that extent easier... to just do what is easier, to do what is more convenient and do exactly that which will lead to personal benefit rather than stick one's neck out and get caught...
why? most say, since it is not conventional, it is not easy and it is more difficult to align the values with the practice... it is thousand times more easy to have values that change with the situation, that are use and throw, but those that can be used to derive benefit...
so why bother to struggle to keep out that gap between practice and preaching since that requires a lifestyle (and here i do mean to include, aspirations as well) that is comparatively more spartan, more honest, more threadbare since the person who does not have a gap, is one who not only sticks it out for herself/himself, but also for others...
and fighting for others need a person who is morally invincible, who is so way up that the ordinary folks cannot even reach up there...
but where are these individuals?
i am searching... do let me know if you come across any.
