“Don't let your ego get too close to your position, so that if your position gets shot down, your ego doesn't go with it.”
- Colin Powell
In Powell’s autobiography he mentions a time when he almost lost his career from a bad performance review. This happened when he was very high ranking at the time. The cause was politics. What happened is that he shared an opinion with his boss that made the boss angry. What saved him was someone who worked with Powell previously seeing the report and validating him.
Our jobs are just jobs. It’s best not to let it become more than that.
