If you really want to do something, you do it. You don't save it for a sound bite.
- Liz Friedman
A friend of mine said something similar many years ago, as a realization he'd had:
"I realized that you either talk about doing something, or you do it."
And it fits with my observations. I think we all know people who are full of great plans, and talk about them at great length. But ten years go by, and none of those things have actually gotten done. And then there are people who actually get things done, sometimes remarkable things, and you rarely hear them talk about these things a lot before they happen.
And of course the same divide can happen inside one person, not only between people. You talk or you do, but rarely both. I'm not sure of the causal relationship. Maybe either talking or doing gets rid of the energy of interest you have in something, so if you are doing it, the need for talking disappear, and if you talk about it a lot, the need for doing it disappear. Maybe. Or maybe if you want to do something and it just isn't happening, but you can't really face up to that fact because you have too many hopes riding on it, you start yapping about it to prop yourself up to yourself.
