You need to know when it’s time to leave.
People often said “It’s better to went down in one blaze of glory (or just in flame, it’s just the same) than slowly rotting away.”
But of course, if you knew when it was the time, you didn’t need to burn.
It rings for all sense and context.
And nothing is sadder than
after you previously left with your head high and your pride full.
Only to leave again later with your heart broken into pieces.
