I'm a big fan of ongoing education. I'm constantly taking courses to improve my writing and marketing processes as well as reading non-fiction. But I also take classes for topics that interest me that I never learned in college. I don't think we should ever stop learning in life, and with so many places to take free or low-cost courses online, we don't have to. 

Currently, I'm enrolled in a Complete Digital Marketing Course from StackSkills that was originally $199, but because I happened to be paying attention, I ended up getting the course for $19.  I've only tackled one of the topics included in the course, but it's already made a change in how I approach working with Instagram. 

Below are a list of some of the other places I've used to take classes:

Udemy—These aren't free, but a lot of times they have specials like $12.99 for classes. They have language, design, personal development, business, and so much more! 
Coursera—These classes are free. I took a screenwriting class through here, and because of that, I wrote my first screen play! 
Open 2 Study—This site has both paid and free classes like Astronomy and Financial Planning. 
Alison—Free classes are available there, too, although, if you want the certificate for finishing the course, you do have to pay for it. 

And if none of these strike your fancy, there are plenty of additional options online.  And this doesn't just have to be about personal growth or learning more about your career. 

These classes are perfect to use for research for your next book or article.  If you want one of your characters to be interested in a topic, you can learn about the topic so you know how to write about it. 

But if you are looking for a career change, these online classes are the perfect place to start.  Classes like beginner digital photography, introduction to carpentry, introduction to plumbing, and visual and graphic design can put you on the path to a better future!
