Teaching is very different from coding.
Knowing how to code and being able to teach it are two separate skills. When we have expertise in a subject, it's common to take for granted that we'll be able to effectively communicate our expertise to someone else. Come learn (or re-learn!) how to teach and discover practical examples you can put to work right away. By sharpening your teaching skills, you'll be a more effective mentor, trainer, and team member.
I would like to work with open source projects to create a branch of the tree with all of the best videos for your open source project. Please send me an email if you are interested.
