Right before you die, everything becomes crystal clear. Perhaps that’s just adrenaline, but I believe it’s something else as well: perspective. Nothing puts life in perspective like death. Nothing else makes you realise what’s important to you, what’s wasted your time, and what you bitterly wish you’d spent more of your life doing. The ‘I’ll do it laters’, the ‘one days’: you realise immediately how you shouldn’t have put them off.
Of course, it’s too late now. You’re going to die.
