Samples. You’ll need some samples before you can really begin marketing yourself. Figure out which market you want to approach first, and then find or create some related samples. For instance, if you want to try your hand at blogging, study some successful blogs, and then write a few posts of your own to use as samples. Do this for any and every market you’d want to write for.
When you lack the luxury of time, making money on or offline can seem like an impossible task. How are you supposed to do that when you're working at a life-sucking nine-to-five job? While the stability of full-time employment might allow most to sleep well at night, it doesn't empower your creative juices to search for new income-producing strategies.
