Pride of course opens doors to downfall though at your age it is somewhat natural. Its remedy is to read books that open a very vast vision before us, books through which we become aware that there is so much more to know, so much more to do, so much more to realise and be. Also, one develops humility when one meets people who know the true things. Finally pride disappears as we surrender more and more to the Divine knowing that He is everything and without Him we are nothing.
Affectionately,
