Expressing our feeling about how we saves the day, appreciating how we handle something, how much time and skill we waste on that, expressing all of that and be like, "yeah I got it" or "yeah I made it" or "yeah finally I did it!", imho, it's all totally okay. The feeling of accomplished something is our reward and we expressed that. Being expressive is good. And I think it's also the right time to take another note, we could actually see how many people who don't like it when we're happily expressing the feeling.
