Because you are not your strengths. And you are not your weaknesses. What you did and what you had or have doesn’t define you either.
If you say you’re stuck, you are. If you say you’re just OK, you surely are. And if you say you’re finished, you most definitely are.

Your word has a magical power. We all know we should be really careful and conscious of what we say. Well, now you know why.
