Well delivered, not too fast or too slow, though as James said a couple of places where the end of a sentence went a little bit quiet. Lots of good tips and advice on counteracting the problem of imposter syndrome, and I think it's a subject that there should be more coverage of.
Brilliant thought provoking talk. Good, clear delivery (though a little trailed off in a couple of places), and really good message, and advice for dealing with this situation. Thanks Mark!
