You&#x27;d be surprised how easy it is for teams to do the wrong thing. Most people have too narrow of a focus, not enough perspective, and not enough wisdom to even care about the right things. Without people with experience, vision, and influence often times the right things just don&#x27;t get done.<p>Being nice means not being ruled by your emotions and not slipping into pettiness. If you have a disagreement with someone, do it nicely. Give people the benefit of the doubt. Etc.<p>But on the other hand, sometimes it&#x27;s necessary to do or say things that are unpopular or difficult to accept. The difference is doing the unpopular thing that is necessary vs. being mean because you can&#x27;t control your temper or you&#x27;re just a jerk or you&#x27;re trying to &quot;win&quot; some stupid technical argument. Don&#x27;t be a jerk, don&#x27;t yell, don&#x27;t belittle people, but absolutely call people out on their shit when necessary.
