Is it though? I have found a job and wife that is OK with my foot in mouth disease and think it works better when you sell who you are. Don't get me wrong self improvement is important, but so is telling people who are going to spend time with you what they are going to get.
The fact the I plan conversations does not make me any less of myself. You are mistaking planning with deception.
And anyone I meet will eventually learn all my flaws, but that's an incremental process. It doesn't make sense to just throw each one of them on the first date.
