So after I posted my woes regarding cover letters and no self-confidence, I felt like I was going to have a massive anxiety attack. But your advice helped me off that ledge, gave me something substantive that I could do instead of just pointless eternal worrying. That being said, I took the rest of the day off and knit instead.
While I feel like my confidence is no higher than it was when I wrote my post on Saturday, this week I have sent out several cover letters to jobs that I am comfortable saying I am qualified to do. In a couple cases, probably more than. And it's because your advice helped me "unblock".
