Power of words

There is amazing power within words if you allow it.

Once you label me, you negate me. ~Kierkegaard

What words are the "magic" words that help and destroy? I learned that I need to believe, believe in self which is to believe in the world, the universe and in love...but to achieve that belief I need trust and love myself. To achieve the trust and love, I need to forgive. The first person and truly the only one that matters to move forward and achieve the rest, is to forgive myself.
