[You are saved. So just. . .]
Do your best.
And if you can’t do your best, TRY to do your best.
And if you can’t try to do your best, TRY to try to do your best.
And whatever level of meta you have to go to, where you know, that you can guarantee, that you’ll be able to deliver your best — go there.
[Then the world is better and so are you. And then you are saved.]
