 Correction equals value. If someone's taken the time to correct you and help you, respect that, receive that, appreciate that. Always value someone passing on some wisdom to you, even if it's done imperfectly. Especially people that you know have been around the block a few times, have been in the trenches, have spent their time, done their apprenticeship, learned a lot. They see value in you or they wouldn't be trying to correct you. Correction equals value.
