So, I love the Godfather Part 1 &2 (let's not talk about Part 3), but unless you're the leader of a criminal organization, keeping your enemies close is terrible advice. This past weekend I was lucky enough to catch up with the friend who wrote the above notes and it felt just like old times. There's something special about being able to go years without seeing someone and pick up like you just saw them the other day.
Aside from being nice to hang out with, good friends do two things for you that are utterly invaluable: They see the best in you, but aren't scared to call you out on your bullshit. Clearly my friend knew me well - of course I am wonderful (that's called sarcasm) but I can also be a bit difficult at times, and she didn't hesitate to let me know. Average, run of the mill friends will see the good in you but hold back when it comes to telling you the truth, because they don't think it's their place or they don't want to hurt your feelings. And your "enemies" will only see the bad in you and criticize you incessantly.
I say things like this all the time on this blog but I will reiterate - life is too short to waste around the wrong people. Do yourself a favor and don't listen to Michael Corleone's advice - keep your very best friends as close as you can.
