Each of us possesses passion for different things-writing, photography, running, cooking, dancing, star gazing, fishing, hunting, painting, walking, traveling, sewing, acting, speaking, leading, carving, ad infinitum-and it likely began when someone shared theirs with us.  Likewise, someone will certainly be moved someday by the love, passion and commitment that you have for the things you cannot not do.  Do not be discouraged if they learn to only observe or study your interest, and opt not to do it.  You plant seeds with your passions, but you don't know what will grow from them.
