Love the ideas but I don’t think it’s a stupid goal at all. In fact it’s necessary. If you want to build anything you need an audience. If there were no audiences, there would be no businesses.
Whether they come in the form of readers, users, paying customers — when you look at them, their audiences just in different forms.
So wanting to reach 5k is actually essential (or whatever goal you set) and putting a date makes it measurable.
Don’t determine a goal stupid just because you didn’t reach it. Revaluate it and set a new one for 2018.
Also — Happy New Year!!
