The Russians have a saying—The English translation is something like this: “We thought we hit rock bottom, then someone knocked from below.”
This could be interpreted a number of ways. I have two ideas in mind, the first being: what you think is the bottom, isn’t. There is someone who has been there before and can walk you through getting back to the top.
I also like thinking about it this way: what you think is the bottom, actually might really be the foundation. This is where it all starts and your attitude dictates what happens next.
