Positive feedback is nice, but feedback on how to improve is incredibly useful. I really value constructive feedback and I spend a lot of time on providing helpful feedback when people ask for it. A short statement that a colleague did something badly is not very helpful, but taking the time to figure out how specifically they could improve and providing suggestions on how to do so usually hurts people's feelings less and helps them more. One coworker even specifically called out that they appreciated the time I put into providing feedback. What really infuriates me is that even though I take the time to provide good feedback on how to improve, other people don't return the favor. I'm young and lazy. I know that my work is terrible. Yet no one has bothered to call me out on it in years or given me meaningful suggestions on areas to work on. Constructive feedback might hurt someone's feelings for a few minutes, but if it is provides structure on how to improve in the future the recipient will come to appreciate it after a few minutes to calm down.
