Even if you work full time, you can create some other income doing things you enjoy. For example, I blog and I teach piano lessons 2 nights a week after work. You could tutor, mow lawns, sell crafts, and so much more. Do you like to write? Start a blog (and check out my resources page for help.) You can also take surveys online to redeem points for gift cards or use swag bucks. These are just a few small ideas, the possibilities are endless!
I’ve read a couple of books about creating multiple streams of income. I’m a big believer, just not entirely living that way yet. For someone who dreams of being a paid writer, I hope to develop multiple streams of income (aka ebooks).
