Sometimes our minds say really unhelpful things that are best left unsaid. Sometimes we hold ourselves back from saying what is important because our minds tell us we will look stupid. Instead I would like to encourage you to communicate thoughtfully. To ask yourself what you want to achieve, and then what you need to say and do in order to make that outcome more likely. It is okay to pause.
