This is not a rationalist origin story, because it is not the story of how you became a rationalist. (It seems fairly clear that in fact you are not a rationalist. This is a description, not a criticism; most people are not rationalists, and manage just fine without being rationalists.)
It is also not about "how we can overcome bias", but about how we can (allegedly) overcome one particular failing which is not a bias in the sense that OB is meant to be about.
As an account of how one can go about eliminating (perhaps unconscious) hatred for oneself and others, and replacing it with love, it has a severe deficiency: it doesn't actually explain comprehensibly how one can. (Your central idea seems to be that you should love yourself "as" everything, including things you aren't. That seems pretty incoherent to me. You might try to do it by, e.g., imagining yourself in the shoes of everyone you interact with, and that might be an effective way of having a more positive attitude towards them; is that the sort of thing you mean? And you say that by not loving yourself "as" an X, where X is something you aren't, you're thereby hating others. I think that's obviously false.)
I think your interpolations into the words of William James and Bertrand Russell change their meanings (James's more than Russell's). Since you appear to be quoting them as authorities, it doesn't seem to me a good sign that you have to change what they're saying to do so.
In general, attempts at proselytism are not likely to find an enthusiastic reception here.
To break up the awkward silence at the start of a recent Overcoming Bias meetup, I asked everyone present to tell their rationalist origin story - a key event or fact that played a role in their first beginning to aspire to rationality. This worked surprisingly well (and I would recommend it for future meetups).
I think I've already told enough of my own origin story on Overcoming Bias: how I was digging in my parents' yard as a kid and found a tarnished silver amulet inscribed with Bayes's Theorem, and how I wore it to bed that night and dreamed of a woman in white, holding an ancient leather-bound book called Judgment Under Uncertainty: Heuristics and Biases (eds. D. Kahneman, P. Slovic, and A. Tversky, 1982)... but there's no need to go into that again.
So, seriously... how did you originally go down that road?
Added: For some odd reason, many of the commenters here seem to have had a single experience in common - namely, at some point, encountering Overcoming Bias... But I'm especially interested in what it takes to get the transition started - crossing the first divide. This would be very valuable knowledge if it can be generalized. If that did happen at OB, please try to specify what was the crucial "Aha!" insight (down to the specific post if possible).
