As a consumer, doesn’t it feel nice to receive a little personal touch to the things you receive like a customized product just for you or a handwritten note with your name on it? It’s a good practice for businesses. Business is personal. It’s about relationships.
But as a creator, a business person, an entrepreneur, or an artist, you can’t get discouraged when people don’t support you or buy your products (a note to myself as well). In this case, it’s not personal. It’s not because they don’t like you, your product, your art, or your creation. It’s because they don’t know, understand, or see the most important thing: what’s in it for them? It's about creating or adding value.
Make it personal. But, don’t take it personally.
