Sometimes though some people start to run around blindfolded because of the search itself,- and they just do not see the Answer that has always been in-front of them: because of that, many quit crying instead of pushing forward.
In most cases people succeed only to peek behind the horizon seeing what can or awaits them behind it. But sadly, unknowingly or unwillingly (sometimes knowingly and willingly) they back down from achieving their goals. It isn't always certain why this happens, but from my researches it's mostly because people do not have enough faith in them. In other words: "they just don't have the guts to do it; -to complete what they've started!"
There are of course various types of different reasons, for instance: people are afraid the feeling of pain: Going through all to achieve something, but that something is their goal - and they just do not realize that significance until they give up on it.
But is there an actual reason to quit if you're so close to it that you can almost touch it? Is there an actual reason to quit, if it will leave on you an mark that lasts forever? Isn't it just better not to cry to quit, but to cry to succeed by pushing yourself more and more, further and further, till eventually you'll reach your goal? Think about it, and don't Just Think - Think Deeply!
Remember this! "Pain is just temporary, but if you quit - it last for forever!"
