Do not be tempted to offer criticism to someone today, they do not want to hear it and will only blame you.
No matter what you think of someone or something they are doing, do not be tempted to tell them what's on your mind and offer your criticism. This person is not ready to hear anything negative and if you say it, you will be seen as someone who is jealous or spiteful. Leave it alone and concentrate on you and what you are doing instead.
