Why does thinking "I already know" block my spiritual progress?
Don't come to the guru already sure
Many seekers arrive with a fixed idea of what they must do to reach Ishwar (God) and look only for a guru who will say "Yes, do exactly that." Ego that refuses to listen leads to ruin.
If you sit there out of ego, thinking you already know what you must do, there is no shortage of such disciples and seekers.
