I see your logic. But in all honesty, the belief that I"m strong is more flimsy than my belief that there is a God. I've seen myself make blunder after blunder. Fail others and myself again and again. The belief that I'm strong is clearly untenable, one that I cannot possibly convince myself to accept. My own vulnerability is something that I've long accepted.
What then? What do weak people like me latch on to? I think our society generally looks down at people who are "weak" or accept "weakness." The manly way is to simply grow some balls, damn it!
But weakness has always been a source of personal strength for me. "Become empowered by admitting your own powerlessness"--that sounds like something from alcohol anonymous, eh? But it's something that I personally live by.
But let me stop here, nip this in a bud, as tears might begin to well up in my eyes.
