There's lots of things that can't make it in the world that are worth making. There are lots of great artists who never make it, there are lots of great writers who don't get published - is it still worthwhile? Aren't we glad people are still doing it?
I'm new to the Twitterverse and so I'm attempting to build my followers. I'm trying to be a better tweeter. I try not to tweet too much, just when I've got something worthwhile to say.
I'm not afraid of putting myself out there to someone and then them passing on it. At least you could have gotten a 'yes.' So it's worthwhile to have the cojones to do it.
You got to like your work. You have got to like what you are doing, you have got to be doing something worthwhile so you can like it - because it is worthwhile, that it makes a difference, don't you see?
