I think it's about letting go of the thought pattern of, "well, if this final effort doesn't work, then it's all over." Now, that might be true for more limited contexts, but when applied to big things like "your life", what a damaging mentality to adopt. In my twenties in particular, I had several periods of adversity, and there was nothing poetic about it. Fatalism, cynicism, inspiration, motivation, none of that had any meaning really. The only thing that mattered was just sheer dumb doggedness. Sometimes you persist even when there's absolutely no reason to. Do it anyway, because fuck you. That's what it felt like honestly. Doesn't make sense to continue, but fuck you. And then it gets better, and then you have a good talk with your past self ("wow, look - it worked out even when it seemed impossible that it ever would - remember that") so your future self has something to fall back on in future times of adversity. Resilience.
