Have no fear! Krsna consciousness is very simple, it almost happens automatically if the process is followed sincerely. Mahaprabhu wants us delivered, Lord Nityananda is giving all Mercy, Srila Prabhupada gave everything to free us, how can we NOT get full results if we sincerely take?
No big brain required. Just as one naturally develops affection for one's family members, one who takes Gopal Krsna into one's home, also He becomes Family with time ! Time I Am ! Sayeth the Lord. But He is Godhead, so the relationship is very magickal and superior ! Krsna consciousness is hardly even a rational or logical process, those are not bhakti.
Chant Hare Krsna honestly, offer nice food as one can to Krsna, read about Krsna's pastimes and philosophy, share Harinam with others, take initiation and serve Srila Prabhupada's real mission; these little things are all that is required for easy advancement into eternal loving service in spiritual bliss !
