Just Do it

I have thought of this phrase, made famous by Nike. I see real genius in the slogan.
There are days when I think, "just do it". Why delay- if I get up a bit earlier, if I go ahead and do something that has to be done, if I just put forth that little effort...if I "just do it", then I will be happier in the long run. Life may even run smoother and be happier.
There are days when I can say with some energy behind the voice in my head, "Yeah, just do it! It's easy." There are other days that I hear myself tell myself to "just do it, come on!" in the same tone that I tell the kids to clean up their rooms. This tone may include some cussing at myself.
There are other days when I spit on the idea, and am appalled at my audacity to even say, "Just do it!" because it is just not that simple.
I have thought of this phrase and my varying degrees of optimism for it over the past month.

I keep thinking of a woman runner getting her Nike shoes on for a run. She is sitting on the side of the bed or couch, and she is bent down tying her shoes. I can't see her attitude or her face, but she is just going to "do it." I can then picture her running in a red shirt and black pants on black pavement with her Nike shoes, and she is strong. She is running alone, but she is not lonely-looking. She looks focused. It is a great commercial in my brain. I need to be her. Who knows if she was cussing to "just do it" or if she was excited, all I know is, she is out there and she is strong and she is not relying on anyone else to pull her along.
There's real symbolism there. Whether my goals are spiritual, physical, in parenthood, in my ...whatever, Just do it!
