People make a living at almost anything these days. People even make money playing video games live on twitch.tv.
There is only 3 components to this:
- Consistency – showing up routinely to make something and illustrate your skill.
- Offering – giving others a chance to experience and/or purchase what you do. This is what traditionally would be sales or marketing.
- Patience – waiting to get to a point where you make enough to do it full-time. For most people this is measured in years.
Outside of these three things lie the tactics, but at a high-level it’s not that difficult. The more difficult part is for people finding what they are willing to be consistent with, what fits their personality, and what they are willing to show up daily for no matter how hard things get.
