When you love to do something and you do it well, could this be your purpose in life? There is a third aspect to determining one’s path, and that is motive. Does doing this thing that brings you pleasure serve only the self, or in some way does it help and thus serve others? If the former, then it is a pastime, and certainly you are urged to do things that are pleasureful if they bring no harm to self or others. But if you can parlay a pastime or a vocation into something that serves the greater good, raises Consciousness, and brings more love into the world, then you will find fulfillment beyond measure. Whether or not this activity fills your coffers, such a gift is indeed a treasure.
For as long as I can remember, I wanted to be an artist. However, I’ve spent near a lifetime forgetting that and then discounting it as being selfish and not serving a greater good. I call myself a dilettante; I tell myself that I can work on this or that artistic/craft project when all other work (all other more important work) is done—and more “important” work is neverending. And so how does one measure whether this or that serves to help others in some way? What about the artists and crafts people: writers, painters, quilters? What about the person who does not feel called to any profession, but longs to be connected to all? What about the monk who sits in solitude for years on end? Is it not enough to live a quiet life, creating as one feels inspired, being a witness to all that is?
My heart tells me the answer to your question is that the individual’s heart (which is always connected to the One Heart, knows when it is “enough.” Did the creative efforts raise the artist’s consciousness? The writer’s? The monks? If yes, then when that monk or artist or writer does interact with others, will they not be doing so from a higher place? Does that not, then, serve the greater good? :-)
