When nothing seems right...

...what should one do? Fix things one at a time, or just blitz everything to obliteration and start straight from scratch? Is there a limit to what's fixable, so that you know when you've gone beyond that limit (the point of no return), it's better to just get rid of all the broken and irreparable and begin with a fresh clean slate.

And what if it's your life we're talking about here?
