3 x interviews

I had 3 interviews this week. A veritable bonanza of opportunity. Two of them I am desperately keen on but, in true Dave style, I feel very negative about how they went. Neither were a disaster but I feel they didn't go as I had hoped. Do they ever? The 3rd I felt went well and I was a dead cert for the job. Didn't get it. There is a pattern perhaps? In a coffee shop mulling over events. Past present and future. Coffee will bankrupt me!
