I'm serious...you are a genius. Perhaps you've never heard that about yourself before now or if you have, it was taken as a colloquial way of expressing delight in some one thing you said or did on one particularly poignant occasion. That's not what I mean. You are truly a genius, or at the very least the spark of genius is within you. The thing that causes us to identify others as "genius" is within you...I promise. 
Supposedly, Albert Einstein (one of our more celebrated geniuses) once said, "Everybody is a genius. But if you judge a fish by its ability to climb a tree, it will live its whole life believing that it is stupid." Now, whether he said this precise thing or not, he did compose a body of allegory that expressed this sentiment. If we judge any person or any creature according to criteria external to their being, then we cannot possibly expect that person or creature to excel within that set of criteria. I believe it's relevant to note that Einstein did not speak until he was four years old, did not read until he was seven, was considered below average by his parents and considered "mentally slow, unsociable, and adrift forever in foolish dreams" by one of his teachers. This is the very same person who developed the theory that measurement of time and distance varies based on how things move in relation to each other (in other words, Newton was wrong...space and time are not absolute). He also went on to: propose that light exists not only as wavelengths but as particles (he was right), invented a new method of counting and measuring atoms and molecules, then proves his own theory of relativity with the now famous equation E = mc2 (The energy content of a body is equal to the mass of the body times the speed of light squared). If you don't quite grasp that, don't worry...neither did Einstein, at least not at first. He felt it. Before he understood it, he felt it. Not bad for a mentally slow, unsociable dreamer, huh?
In 2002, literary critic Harold Bloom published his book "Genius" that explores the lives of 100 literary greats that he identifies as geniuses. I've enjoyed this book over the years as I return to it now and again, and I've concluded that there is a common element within each of the 100 designees, and that is passion. It is abundantly clear in the body of work produced by each of them that they were (or are in regard to the living honorees) deeply passionate about their various subjects. Passion is the spark of genius (yes, you may quote me on that). I will repeat it for emphasis: Passion is the spark of genius.
You are passionate about something. Oh, it's very possible that others have done a good job of helping you bury that passion by encouraging you to pursue something else (ususally THEIR passion), but I assure you, you are passionate about something and within that passion is your genius. Being a genius does not require you to have an extraordinary IQ like Einstein or to play the cello like Yo-Yo Ma. However, expressing your genius does require exploring, discovering and sharing your passion. 
So what is your passion? Where is your genius? You may already know and may very well be expressing your genius...congratulations, and thank you for sharing. But if you don't know or if you do know and you're just not prepared to express it, don't worry, just know it's there.  
Jesus was once asked when the kingdom of God would come. He replied that the kingdom of God is not something that can be seen or pointed to but that "the kingdom of God is within you." (Luke 17.21) With these words, Jesus expresses one of the most prevalent precepts in every great religious, spiritual and wisdom tradition, that life's greatest truths and treasures lie within us. Plato called it the "Good and the Beautiful." Aristotle referred to it as "The Infinite," St. Bernard of Clairvaux as "The Word," and Ralph Waldo Emerson the "Oversoul." Taoism identifies it as the "Tao," while Judaism calls it "Ein Sof." Here, I'm calling it "Genius." After all, what is "genius" but the expression of beauty and what is more beautiful than the expression of divine light? What is "divine light" but the very energetic essence that forms the entire universe?
On Ash Wednesday, Christians receive the imposition of ashes on their foreheads with the words, "Remember that you are dust and to dust you shall return." I think I will amend that a bit as I encourage you to seek your inner genius by saying, "Remember that you are stardust and to stardust you shall return." The molecules that comprise your being were once part of the cosmos (and technically still are as we float through space on this blue marble) and the energy that fuels your thoughts, hopes, dreams and passions has existed in one form or another forever. "The kingdom of God is within you." The spark of genius is within you. 
I will leave you with this thought as expressed by David Orr, "The plain fact is that the planet does not need more successful people. But it does desperately need more peacemakers, healers, restorers, storytellers and lovers of every kind. It needs people who live well in their places. It needs people of moral courage willing to join the fight to make the world habitable and humane. And these qualities have little to do with success as we have defined it." 
You are a genius. Exploring what that means for you and sharing the results with the rest of us is true beauty, true light.
