The point here isn't efficiency, this is basically the bare minimum I think one can do while still learning and making progress, i.e. you don't need to follow a rigorous schedule or cultivate a great deal of self discipline if you enjoy the task. Doing even 20 minutes is always better than nothing at all.
Do this and slowly build up discipline by pairing it up with consistency.
