Do you feel like if you accepted life as it is and as it can be, within its limitations, absurdness and pain life would become livable ?
Its much easier said than done
For example, slaving away at a job for 40 years. You can either hate it and dread it. Or accept it, then instead try to enjoy your daily cup of coffee while you are working at the job
In the end, its not going to make a huge difference, and lying to yourself can only last for so long, until it loses its effects
However, as an absolute last resort, yes, that can be considered a strategy. But just expect bare minimal effects
Because I'm assuming you refer to lying to yourself for a few decades, which is not a short amount of time. Unless its just a few months, a year, or even a few years, then might be possible
This is probably a coping mechanism people use when they're stuck in prison
