I did one of these little online seminars that was called Improve Your Confidence While Job Hunting or something. I ended up feeling even less confident than ever. We were told to do things like listing your achievements so everyone except me came up with things. I don't think I've achieved anything recently. Then we were all told to do some exercise and that Couch to 5K would change our lives. I have my own personal reasons for not wanting to go running.
I'm not interested in personal development advice here, I'm just annoyed that I wasted a few hours on this seminar.
Please cheer me up with tales of courses that left you none the wiser or did the opposite of what was supposed to happen.
A friend of mine once said she went on a time management course, and left early because she had better things to do with her time.
