The mind can be very trivial if you let it wander on its own. It will have you thinking of things that are less than who you are. It will look through its database of old thoughts and consistent thoughts that you think and will bombard you with them. In these times, it is our responsibility to recognize when this happens and immediately alter the path by choosing to think about things we enjoy. At first, it will sometimes be challenging to recognize when you are going in the wrong direction but as you practice and not beat yourself up, it will become easier and easier and you will notice when you are about to spiral in the wrong direction.
The key to all of this is loving yourself enough to refuse to be taken into places that make you feel less than.
Enjoy your journey to wholeness.
