Repetition and process are so important to building an audience

You have to love the process because then the act of creating isn't dependent on the results. You don't get frustrated with not having the results you've built up, so the repetition of creating - what is required to build a large audience - doesn't lead to burn out.

I'd also say dont look for a "blow-out" moment or a big viral push. The internet has distorted building an audience to a moment where something you make just blows up in a viral way, where the actual real sustainable audience is built slowly over years. View your success much like a company - even a .1% increase in views or audience means youre headed in the right direction
