I'm not trying to be super negative here, but I'm starting to learn, even more so, an important lesson about being in leadership positions. You sometimes need to make a decision and often you will upset somebody. No matter how much you think about the consequences, there will be people who think you made the wrong choice.
It is easy to let these things get to you, it is very easy to feel like you're making bad decisions. I keep coming back to the idea that I should focus on those that appreciate the effort you have put forth. Sometimes this is just hard to do though, it's not easy to put aside criticism. This is especially true when the other person has a valid point. I just need to stand by how I felt and the logic behind my choices and trust that I made the right decisions.
