Mine was not a personal attack; I attacked the content of your message, which I do not think is helpful at all to the OP, not your character, intelligence or person. As for your counterpoints, they are valid in the sense that no solution is perfect, but the cons involved in using something like 1Password, especially for the OP's case, is better than the alternatives, including the one you suggested.
And to be fair, let's be honest, it's not really a reasonable suggestion. Unless you disclose your mental organization strategy, it isn't very useful for the OP, now is it? To me, the reasons for not disclosing password management/creation are not obvious, unless they are formulaic and can easily lead to your own actual passwords, in which case, I don't see how it's better than pseudo-random password generation. Or maybe they don't exist. Just saying.
The fact is, what you suggested really isn't useful to the OP. That's my problem with it. I attacked your post because it is harmful advice. Maybe it works for you, but without knowing how you do it, it won't work for 99% of people out there (maybe it won't even work for most people even if the knew how you do it, which you aren't disclosing anyway), and as such, it constitutes really horrible advice. The average person who sees your post and takes your advice won't do your magical, fancy pants mental algorithms, and will leave themselves susceptible to password theft.
You basically said: Do X, which requires doing Y or else it will totally stupid. I'm not telling you Y though.

No machine random generators are truly random, but the human mind certainly is not either, and reverse engineering the generator shouldn't be a problem as the hacker would not know any of the information regarding seeds, when it was generated, possible hardware specific identifiers, etc that may or may not be required in the algorithm.

I'll agree with you here. A physical notepad is probably the worst thing to do. (edit: digital is pretty bad too).
