100% agreeAs a trainer this is where I would pull you aside and make sure we are on the same page. Making sure you know that you do a lot right (pep talk) and we can try a hundred different things to correct your recurring mistakes. As a trainer, if I know that you will put the work in to certify I would do anything to help you. Make sure you are showing that every day, 100% of the time to all of your coworkers too. They may be able to come up with stuff to help you too. People are watching, believe me. Hopefully, this is a temporary block and you can move forward. Good luck.
