Nothing is more important than who you consider admirable (for by nature we automatically imitate who we consider enviable – so ask yourself "who do I consider admirable?" – if you find you are admiring a bully or someone who just is delusionally grand, remember, when he is two feet under, being eaten by worms as God says "I will humble all the arrogant"… while those who are humble, say the Rebbe (in fact God gives us in every generation someone of sterling character to emulate but because they are so humble, often our ego is not attracted to them) they remain eternally great!
