Write down your negative thoughts on a piece of paper. Think about how they influence your life. Then tear them up, shred them, soak them, anything you wish to destroy that thought.
You can also write a negative thought on a blank card. Especially the thoughts that are more prevalent and affect your daily life. Then write the alternate positive thought on the other side. Keep this card with you and when you have the negative thought, you can look at the positive alternative and help change the thought permanently.
PARENTS You can help children write down their thoughts and help them shred them, or tie them to a balloon and let it go. Or keep a card with them to remind them of the positive affirmations.
