I've refrained from joining in this conversation to avoid stepping on toes, but anyone who knows me knows that this fear won't hold me back for long. Additionally, I am not an elf and so I cannot speak from experience, feel free to disregard whatever it is that I have to say.
With that said however, it is my naive belief that if you are looking to be the best elf, you must only be the best you. By whatever twist of fate that has occurred, you are now an elf. Whatever changes that may have happened will have already taken place. Your body may have changed, you may have found the ability to connect more deeply with nature, even parts of how you think might have drastically been altered. Those things, whatever they may be, are a part of you now, immutable and firm. Perhaps you feel no change at all and all of our differences but for age and ears are imagined.
Unless fate chooses again that you will change your race, you are an elf. What you should be concerned with is not what makes a good elf, but with what makes a good you. Search out those changes, no matter how small, and accept them. Continue your search for purpose in this world and build meaningful relationships with others. Use the years you've been given to be kind and make the world you live in a better place.
Ignorantly yours,
Tvard Sendall
