Whenever I work for someone new, I hate the anticipation that comes with waiting for initial feedback. It stresses me out to the point I am convinced they hate it until they actually say anything positive about it (and even then, if it's generally vage then I still don't believe them). I think it's because I don't actually like any of my work. Or more so, I don't think I am that good so when I see what I do for someone, I always think it could be better.
I had this the other day with a client. Thankfully, he was happy and loved the website. On the flip side, I'm doing a 'love job' for someone and I am nervous to think what they think of my initial idea. Granted, they have me zero guidance for the content other than colour but I still worry they see it and think, "Oh, that's not that great."
There is a difference between someone not liking something, and something being bad. I can usually tell which side they're taking if I'm with them in person. Over email I can't and it's absolutely awful.
