The idea of always saying the first thing that comes to mind is great in some ways. However, it doesn’t work well in every situation.
If you’re someone that excessively analyses everything you say before you say it, practicing to say what comes to mind could be a great way to combat your anxieties.
But if you’re someone that is quick to react and easily enraged, taking time before you speak could save you a lot of hassle.
It’s useful to look at certain aspects of yourself and think about what works well and what doesn’t. The result of that self-reflection might make you realise that you need to think more about what you say or think less.
