I posted the first chapter of my memoir's rewrite in first person since the other version wasn't able to catch the interest of any agents, and I am wondering how long one must make a memoir to be able to interest an agent. Is 60,000 too short? The previous version was in the range of 70-80K but I don't think I can make this one quite that lengthy since it's in first person. So what do you think the bottom end of the industry standard is? 50K? 60K?

Thank you all in advance for the advice, I hope that I can do it right this time, so far it feels right but then I haven't gotten any feedback yet on the posting I did two days ago, so I am eager to hear what you think about the length issue to put my mind at ease as I am about 20K done on the first draft.
