Open Yale Courses echoes Harvard Extension and Stanford Online, in that it offers only courses from Yale. While the site is similarly limited to topics taught at the school, Open Yale Courses offers a lot of videos of actual campus lectures. The availability of videos makes the site a great option if you’re looking for quality courses, but learn better by watching than by reading.
17. Amazon – Have you heard of FBA? It stands for “Fulfilled by Amazon” and it’s getting pretty popular. Basically, you buy products (in bulk is best) and ship them to Amazon for them to store. When your products sell, Amazon packs them up, ships them out and sends you the money (after taking their cut). There are people making a full-time living from FBA, while others just do it for some extra money.
