In this generation of social media, we daily encounter many advertisements of paid online courses. We look the Intro video and expect so much from the course and from us to do extraordinary things after the course completion but most of the time with most of the people is that they actually dont complete courses due to their personal reasons. So at end of the day all they are doing wasting their money. So what I say is that if u wish to buy a course, first learn the basics of that course on ur own and after learning those basics if u r still interested to buy that course then go for it. If u really follow this method, most of the time people dont spend on the online course because in their research they find so much of info for free and after knowing basics of that courses, people understand the basic keywords and when they know what they are actually looking for most of the time the content will ve available for free.
