I guess this is just a riff of marcus aurelius flavour stoicism

but ask yourself with regard to every present difficulty: 'What is there in this that is unbearable and beyond endurance?' You would be ashamed to confess it! And then remind yourself that it is not the future or what has passed that afflicts you, but always the present, and the power of this is much diminished if you take it in isolation and call your mind to task if it thinks that it cannot stand up to it when taken on its own.
