A solid indicator of your life's path is your friend count. In general, the more people in your immediate social circle to help you get through life, the happier you are going to be. A good number to shoot for is 30, but anywhere between 10 and 25 close friends will probably do the trick. When you have lots of buddies to chill with you, you can at least appear to be happy.
Oh, and this means real-life friends, not ones you met online.
