But stray away from any of these 'goals', for whatever reason and by however small a margin and you won't stop hearing about your 'good friend' who did all the things you were 'supposed' to do and is now the poster child for every other person that has 'goals' and is 'career-oriented'.
Life is difficult man! Don't let peer pressure get the best of you :)
