The Universe likes people who are creative, people who dare to be themselves. Name and claim for yourself what you choose to be (don't worry, you can always pick a new path later, if you decide you don't like it). Don't say, "I wish I could be..." or "I want to be...." Say, "I am [whatever it is]." This is forming an intention, the exact opposite of a wish. You may find the book The Artist's Way by Julia Cameron to be helpful. You can read the word "artist" in the broad sense, to mean any creative endeavor. You may find the simple exercises in that book helpful.
Speaking of naming and claiming for yourself, "Misswisdom" is a powerful name. Praying for wisdom is a risky business. The Universe (also known as Spirit, or God) grants wisdom, but usually teaches it through suffering. Whatever happens, ask yourself what is the lesson here? Oftentimes 90% of passing a test can be just seeing clearly what the test is.
Ah, we older folk do like to listen to ourselves talk, don't we? But you wanted action, not words. Here is your spell:
By the Lady of Life, Source of the Springs of Being, Mother Earth and Queen of Heaven, may you be Blessed as you walk your path, may your life be filled with Her transforming power, and may you take the reins of your own destiny and ride in the driver's seat of your life.
It is done. (now give it a minute; magic grows like a baby dragon, taking its time to come into its power)
