Life is simply a test of strength. Some people can make it 'til the end, so they're able to see thier final grade and others quit halfway (suicide). Nobody ever leads an easy life, which is why I think of it as a test of sorts. It's like a pop quiz. Things are goin' smooth until the teacher (or in our case, God) says, "Quiz time, b****es!" and puts all sorts of hurdles in our path. Just to see how well we deal with them.
That's what I think at least.
