What are you good at?
Ask yourself which of your skills could be worth selling because not every skill is a service. For instance: making enormous chewing gum balloons may be impressive, but it won't secure an hourly rate. Making pretty braids may also be an admirable skill, but until you perfect it into something that will bring value to paying customers, that's all it will remain.
Another supreme example is being acquainted with a foreign language. First off, how good are your writing, listening, and speaking skills? Even if they're at the highest level, do you know how to use the language? Speaking a foreign language doesn't necessarily imply you'll be able to translate to or from it, nor that you can teach it to others.
Think hard about what you're good at and if you can make a living out of it before proceeding further. But don't forget: you'll never reach a point of perfection. It's better to start small than building skills to infinity while being unable to cash them in!
