Online Courses
Creating online courses is a great way to have a business which reuses the same content over and over. If you create an online course you only have to do the work once and can continue to make money from it well in to the future.
Many people want to learn things without attending formal education these days and there is a growing trend of people wanting to learn from home.
If you have a skill or area of expertise then creating an online course could be easier than you think.
