Stagnancy is death.
If I have to choose between being stagnant or having to move backward, I would choose the latter.
I would rather move backward than to stay at the same place for the rest of my life, because stagnancy is the worst stage of one's individuality. Not moving at all is death itself in the midst of living. I would rather crawl just to keep on moving.
And not because you moved backward means you're lost or you're defeated or you don't have any direction in life... Remember, life is like a chess, to move back doesn't mean you are losing... It means you have a different route to win the the game.
