I don't think it's a good idea to force yourself to do something you're not entirely convinced of..
I think the right moment will come without planning it too much. Life always surprises us with a lot of negative things... until we finally get fed up.
I'm afraid that moment would never come for someone like me. I'm so resilient to negative life events because of my specific mental illness; it's a state of homogenous and steady misery no matter what happens. Not even close enough to use it as CTB fuel; something is really wrong with me upstairs.
It's almost like a superpower; you can call me Capitan Miseria.
The only way I have of CTB is forcing myself to do it , sort of acting out my impulses.
I'm not advocating for op to do this btw, everyone's brain is different, i just wanted to share my own experencie.
