Feel of lost is something like..

When u'r ready to obtain something, that u'r feeling pretty cool abt it. Then u were told that u did not... And so you feel lost.

As i learned in my math lesson, u need to get to the result little by little, step by step...
And as I read in The Old Man and the Sea, that it is better to be lucky, but one would rather be exact. Then when luck comes he is ready...

I should say that I understood neither of them, but I would rather that I knew them. cuz if i knew them, i would not be soooo "unlucky", that i missed sooooo many opportunities that i could've got.
