A seeker doesn't see what is under his nose.

"When someone is seeking" said Siddhartha, "it happens quite easily that he only sees the thing that he is seeking; that he is unable to find anything, unable to absorb anything because he is only thinking of the thing he is seeking, because he has a goal, because he is obsessed with his goal. Seeking means: to have a goal; but finding means: to be free, to be receptive, to have no goal. You, O worthy one, are perhaps indeed a seeker, for in striving towards your goal, you do not see many things that are under your nose."

Herman Hesse, "Siddhartha"
