vapourmile, at the risk of being reductionist and emotional, it looks to me like your inspiring purpose is to be of service, to be contribution!
Here in these threads we've been talking about how to distinguish an inspiring purpose for ourselves, and it may look to you like there is no intention to act on that inspiration. Please keep in mind that the "purpose" threads are pretty specialized; in other threads we talk about how to actualize the purpose or how it's showing up in our lives, but sometimes we focus in specifically on distinguishing it. I agree with you that a purpose living under a glass bell, untouched, isn't worth much. And I think the people who participate here are interested in inspired action.
You're right that inspiring purposes tend to all sound familiar -- we all have so many of them in common! Purposes that involve love, peace, contribution, freedom... we are seeing some things that we all want, things we all want to generate.
And...declaring a special "genius" or dynamic intention to live purposefully is a tool we give to ourselves, so that we can boldly make a difference, so that we can see for ourselves, in a specific and measurable way, if we're satisfied that we're living a life of inspired action. Of course, some people, sometimes, will not be satisfied that they are living lives of inspired action, and some people, sometimes, will not care. But please consider that the folks here are really up to something.... making a difference, and being in love with their lives. We're generating making a difference, right now in our lives in a practical way, nothing spooky or whoo-whooo about it. You can rain on the parade, but is that how you want to make your difference?
Looking at the list of your seven special intentions, I think you are up to something really wonderful yourself!
( By the way, my new special sweetheart of feeling good on purpose is Paul McKenna, who is, of course, a Brit! )
