Hence my issue with this: If you need to use (1) "life is meaningless" as a stepping stone to (2) "therefore, life has whatever meaning you give it", you've already agreed to that constraint by default. I'm sure it helps a lot of people get from (1) to (2), but better still is to realize (2) is in a sense _deeper_ than (1) and you can just throw out (1) once you have (2) locked down enough in your psyche.
That's not the same as life having no meaning, just not an inherent one. A fireplace is not inherently burning, but if you stack a bunch of logs in there and light it, it will burn all the same. The meaning of life is just the same. The physical reality of it is at it is, but what you do with it is up to you. You can follow the path laid out before you, like lighting the fireplace, but nothing's stopping you from grabbing a knife and running off to the woods to run with the wolves if that's what you'd rather do. Nothing but yourself, anyway.
But you're still finding meaning in the abyss - you're choosing what to live for.
Which is great!
Most people can't get there. They stare into the abyss, and run screaming back to some false comfort.
I stop asking questions once I am satisfied I understand something, not before. Sometimes I'll leave a question for later, to give my brain some time to digest it, but besides that, I'm always working through something or other. Just gotta ask the right questions is all.
