That's half of it. Next 50% is your morale! You ARE going to go in there and you ARE going to show that despite not nearly having enough practice, you ARE going to produce a creditable performance which may not be the best they've ever seen, but considering your basic lack of practice, it is still going to be damned impressive, and it will be a privilege to sign your licence so you can get out there and get paid to have more practice and really show them what you can do when you are allowed to get some proper training in!
Did you follow all that? Are you going to whap their ass next time?
