Rhetoric is about dissolving the personal ego and getting down to matters of individual & social truths, and writing is rhetoric, even on a message board. Where you're from, what you do, how much money you make, etc., are all ego driven and bias the truth. Strong social societies are driven based upon respect and understanding, and the ability to educate & interact without bias. The dice will fall where they may, but it gives no one the right to judge. You sometimes can't help how you feel and react, but you can try. You should never stop trying to become a better person--there's always something to learn--there are infinite angles to any situation.
People come here with problems or wanting to learn something. The best we can do is educate, and it's not a quick process. Patience is necessary. Our jobs as regular members here, if you want to call it that, is based upon repetition. Our reward is the success of another, and it's a worthwhile cause. There are many that come here and leave far more educated and happy that they've achieved their goal. YOU played a part in that. YOU were part of the team, even if you knew it or not. Just because you aren't singled out and rewarded with praise doesn't mean no one cared about your advice.
Fish keeping, in and of itself, isn't really that difficult--it simply takes effort, but to get the most out of it requires the ability to get the most out of another person or group. Be willing to learn because people love to share. Social skills will generally dictate your ability to succeed in most any situation.
