You know the moment that you say: "I'm gonna give my all to this one last time. I'll use my very very last drop of myself to fix it and it's gonna be fine"
And you give your all!
And it's gonna be fine... But only for a minutes! And then it wants more! And then you comply with it! You give all yourself to it one last time! And it's gonna be fine... for a minute... and you comply..
as Homer Simpson has delicately put it: you did your best and you failed, the lesson is Never Try
wish you luck Arthur
