not miss for the world
not miss (something) for the world
To be unwilling to miss seeing or experiencing something no matter what other things might get in the way. Don't worry, sweetie, I'll be there to see your performance tonight. I wouldn't miss it for the world. There's a big project that's coming up the same month I'm travelling to Paris,, but hopefully my colleagues can handle it without me because I'm not missing this trip for the world!
