What matters isn't how you fall. It's how you land.
It's the story of a man who falls off the roof of a 50 storey building. As he sees the windows rush past, he thinks to himself: "So far, so good ... So far, so good ... So far, so good". All the way down, he reassures himself: "So far, so good ... So far, so good ... So far, so good". But it's not the fall that matters. It's the landing.
There's two ways to read that story:
1- It's not your failures along the way that will define you, but the way you succeed at the end (the story doesn't say what is waiting for the man at the botton of the building)
2- When things get scary or difficult it's tempting to look only a little way ahead to avoid seeing the inevitable big picture (just one cupcake, just another drink, just a few days slippage won't be a problem). But that's not going to prevent the spectacularly awful ending that's coming your way.
How do you read it? What can you do about it?
