When being criticized most people have the tendency to get defensive.When getting criticized the first thing I would do is remain calm, listen, and realize everybody isn't perfect including myself. For example do you think Garrett Morgan was perfect? Do you think he was ever criticized? Well to answer the questions no, and yes he was.
Now the next thing I would do having a peace of mind is look over my work and check for errors. When I locate the errors fix them. For example if you're putting together a bassinet and you notice something is wrong you simply go back and fix it. Lastly and most importantly don't ever take anything said personal. You have no idea what people are going through or how rough there morning or evening was so be humble.
