In the Wizard of Oz, Dorothy has the power to return home at any time (thanks to the ruby slippers) but she didn’t know it until Glenda tells her so at the end of the tale. Our lives are filled with examples of having power that we didn’t know we had.
Take a few minutes to think of some times you had the power to accomplish something but didn’t. For example:
After year of using Microsoft Word, I discovered the Format Painter. I used to format each bit of text individually. Now I format one bit, then use the Format Painter paintbrush to format text by running my cursor over it. It takes a fraction of the time and I make a lot fewer mistakes.
