Online courses and Digital products are bringing great income to people now. I myself was highest earning instructor at Skillfeed and doing really great on Udemy too, also having my own website hosted on Zenler as well. However for a new comer it seems very intimidating and is a difficult task to accomplish. There is lot of information available online but since I have been there done that, I can tell you almost 90% of the online info is crap and outdated.
Things have changed a lot and If you really want to succeed at online training then this one Podcast by Pat Flynn is enough for you.
Podcast are great alternatives for delivering research content or lessons to students who need remedial or extended support. Since they also bring great earning opportunities through sponsorship more and more people are using them to add to their stream of Income. Hence it also becomes imperative for the Podcast to be of high quality and deliver valuable content and the above one is surely one of them. Any how a discussion between greats of the niche is worth listening.
