This is Julia, the OC. You're totally right that we didn't realize how hard raising money actually is. A lot of other founders I've met also don't realize, which means they're disappointed and discouraged when they try. The point of this post is to encourage founders to keep going even when they're down. I almost stopped fundraising a month in because I was so down, and now I'm grateful that I didn't.
Everyone has imposture syndrome when raising. I wrote this post to let founders know they're not alone and to not lose their self-confidence because of investor rejections.
