You have all the info you need in the Chad Ward article and the videos to get started...it really is just putting in the work and getting more practice.
We've all went through these struggles when starting, so don't feel frustrated that you didn't get it the very first time out...it is a process that you will continue to get better results with over time. Just don't give up on it, I promise it will pay off soon enough.
The muscle memory of holding a consistent angle is most important early on, so beater knives are fine for this; however, move onto the Tojiro when you feel comfortable--it will feel better on the stones, burr abrasion/removal much easier, etc. than a crappier steel knife.
Have fun with it!
