Suggest Robert Twigger on Good Work Habits

This is more of an "I think this is interesting and possibly useful". It relates to "work ethic" in the README, and it relates to patterns of behaviour for participating in Open Source. Also if I were to get my way and put in a section on how to learn, it would relate to that as well. Oh, it also relates to onboarding developers of varying degrees of experience. I found it useful as a perspective to consciously think about whatever projects. Therefore I suggest:

+ [The Real Secret](http://www.roberttwigger.com/journal/2011/11/8/the-real-secret.html): "The skill is so simple to describe I’m surprised I’ve missed it all these years: the ability to turn workish stuff into work."
+ [What Level of Job Can You Assign Yourself?](http://www.roberttwigger.com/journal/2018/3/3/what-level-of-job-can-you-assign-yourself.html): "what level of task can I assign myself and carry out successfully?"
+ [Give Yourself a Task Ladder](http://www.roberttwigger.com/journal/2018/3/3/give-yourself-a-task-ladder.html): "Use the task ladder to work up to giving yourself truly huge jobs you can successfully carry out".

Interestingly, I think learning resources should be structured upon a "task ladder", with clear description of prerequisite information and skills. It would be a better way to create the [rapid learning effect](https://www.youtube.com/watch?v=8PVeLqWnaXk).
