At the end of the day, kindness and compassion matters in all human endeavors, because we are fundamentally emotional creatures, even when we do not want to be. Look at how you respond to something unexpected in your IDE– most of us feel annoyed, slighted, or even angry when the computer is not kind to us. We’ll explore what aspects of the applications you write might be eliciting negative feelings in your users. As important as that is, it’s also critical to extend kindness throughout the development process and your career. That doesn’t backing off what you know is right, it means accepting that you may be wrong, really listening to those around you, and treating everyone with decency and respect.
