We are all busy. We are definitely doing something wrong.
We have more things to do today than we could do in a whole week. More often than we’d like to, we produce things and forget we have to "sell" them.
It does not matter how good what you create is, the need to market it is always there—people need, somehow, to know about your product. There is no way they can give it a chance if they don’t even know it exists.
Along the same lines, you need to let them know what you are up to. No matter what you are doing, it is extremely important to give your potential customers a way to keep track of what you are working on—especially if what you are pursuing is to build a tribe, a community. May it be a mailing list (which you should already be rolling out), an RSS feed, or a social media account, your users must have a way to follow your work, one that they are comfortable using already. The best case scenario is, probably, a combination of all of those mentioned, so the user can choose how she'll be hearing from you.
It’s one of my biggest business mistakes, not setting up an email list for several years. —Ramit Sethi
Giving people a way to know about what you are doing is key to any activity that relies on a tribe. Even more important, is providing users who value your product with ways to pay for it. Remember that store that couldn’t take your money because they didn’t accept payments by card? The worst thing you can do is having users willing to follow and pay for your work and not letting them do it.
