Course Description
Online Course Creation can be highly rewarding and profitable if you execute a successful strategy. Or it can be unprofitable and frustrating if you don't respect the medium.
"TJ Walker is a foolish man who has made numerous stupid mistakes. Anyone serious about being successful in the online course creation business should study want TJ has done and then do the exact opposite!" TJ Walker
This course is different from most online course creation Udemy courses and is different from most Udemy courses in general. This course is a candid, transparent account of one online course creator's failures over the years to master this medium.
TJ Walker has many of the top-selling communications courses on Udemy, but he also has created scores of the worst selling courses. This course is a chance to shorten your learning curve and bypass the time-consuming and costly mistakes that other online course creators frequently make, but rarely talk about in public, until now.
Please note: this is not the course to take if you are looking for technical advice on what camera or mic to buy.
Note: this should not be the first or only course you purchase on online course creation. This course is meant to complement the online library someone has if they already have a handful or more of courses on online course creation and they want to round out their knowledge-base before advancing their online course creation career.
A final note from the instructor: this course is not in any way an "official Udemy course" created by anyone who works for Udemy as an employee, but I suspect that they wouldn't find much to disagree with inside the course.

Exactly what I needed. Enthralling from the get-go. TJ makes the time to answer every students questions. provides resources including a Facebook Support group (in addition to the Q&A discussion page) and is engaged. You can tell he cares about his students and that is great for motivation. I highly recommend this course, and this instructor in particular.

I'm thinking to create a course and this really gave me an insight of this world. One suggestion: use any other background that you think is good instead of white. I'm watching this course at night and its not comfortable.

Contrary to some others, I liked the "old" background + his suit-and-tie. They gave the lessons a more serious atmosphere right from the start. The TV screen background wasn't distracting at all but instead provided some relief to the eyes when you need to look away rom the instructor for a few seconds. Some of the negative feedbacks might have originated from competing instructors trying to sabotage a good thing. This kind of behavior happens in real life all the time.

This bloke is unloading about his failures in his previous endeavours at course creation. Nothing yet about actual course creation content.
By Tina Emm on 9/26/2020
Mir hat besonders die Art des Sprechens (akzentfreies Englisch), die Beleuchtung und die Ruhe des Dozenten bei der Präsentation gefallen. Das Ganze wirkt sehr professionell. Ich habe nicht viel Neues gelernt, jedoch habe ich Bestätigungen für meine Pläne erhalten. Ich schätze außerdem die Offenheit und Ehrlichkeit des Dozenten, sofern ich sie einschätzen kann, das macht das Ganze glaubwürdig für mich. Er ist als Person der professionellste Dozent, den ich auf UDEMY bisher gesehen habe.

There were good tips on course creation. in particular, using the Udemy "free" courses, accessing other courses similar to yours to see what they cover and how they do it, to use the Udemy metrics provided in the Instructor area, and others. These were all useful tips. There was a LOT of emphasis on promoting Udemy, which seemed "over the top". There was a strong suggestion to use TikTok, which seems inappropriate given the recent (July 2020) information that it provides data to China. Does not appear to be secure at all.
By Raquel Furchinetti on 7/26/2020
That´s a fast and great course. I recommend mostly to someone that is already an online instructor as me. I would love to see the process of making a course in max 2 weeks since it takes forever to launch each one.
By Kavinah Mos on 9/17/2019
This course is not technical but offers very useful information about blunders to avoid from an experienced teacher. It deals with issues I would not normally think is important. I think the course could do with mini exercises.
By Stephanie Mojica on 3/16/2018
I learned tips in the first two videos that could save me time and earn me money when creating my Udemy courses. Like TJ mentions in the description, this is not the tech course. I'm in two for that from other Udemy experts, and making progress on that end that way. However, I have taken at this point countless courses on public speaking from TJ. I knew, liked, and trusted him — so I invested in this course of blunders to avoid. His perspective is very important and helpful.
By Cuyler Stuwe on 3/10/2018
I found this course for free with a coupon from the /r/udemyfreebies subreddit, so my experience (related to coures value) might be influenced by that. I don't think I'd pay $10+ for a course this short. However, it was definitely insightful and worth the short amount of time I invested in watching the videos. Thanks!
