As developers, criticism is part of our job. Code reviews, user feedback, colleagues' comments - all come with the territory. But, let's face it, criticism can sometimes sting more than an unexpected null pointer exception (okay, maybe not that much, but you get the idea).

Dweck, Ph.D., in her book 'Mindset: The New Psychology of Success'. She speaks about two types of mindsets - 'Fixed' and 'Growth'. If we embrace a growth mindset, we perceive criticism not as a verdict on our abilities, but as an opportunity to learn and grow.
