Re-Invention

I have been using the words "re-inventing myself" a lot lately. It seems to be a more sophisticated version of "deciding what I wanna be when I grow up." The thing is, when I say it, I expect that people will be curious, or surprised, or perhaps a little concerned or sympathetic. But these days, the reaction I'm getting isn't any of those things. What I am hearing, over and over, is "well, we all re-invent ourselves every day, don't we?" I guess I'm not the only one experiencing change.
 
Perhaps it used to be that a life that stayed relatively the same was the norm. A person might get married, or have children, but while these changes were happening, that person's job or mission would stay the same. These days, as I try to find (and re-find) myself, and what it is I was meant to do (which, some days, is as specific as "work in children's television" and other days is as general as "work"), I am realizing that re-invention does happen over and over. As I tell my story, I see that re-invention seems to have become the new norm.
 
So, how do we re-invent on a regular basis, but still hold on to some kind of concept of ourselves, and maintain some kind of living that recognizes our level of experience? If I had all those answers, believe me, I'd share them. If I have learned anything at all, it's that re-invention takes a lot of help along the way. But for now, I'm still in the inventing lab of life, working on my next big thing, waiting for the "aha" moment, or the perfect solution, or simply the pieces that will finally--well, at least for a moment in time--fit together.
