You think it will never happen to you, that it cannot happen to you, that you are the only person in the world to whom none of these things will ever happen, and then, one by one, they all begin to happen to you, in the same way they happen to everyone else.
The best investment you can make is in your own abilities.
Trust is like a mirror, you can fix it if it's broken, but you can still see the crack in that motherfucker's reflection.
