I have completed both of the following:

1) https://www.coursera.org/learn/learning-how-to-learn

2) https://www.coursera.org/learn/machine-learning

I highly recommend both of them, if they cover a subject you're interested in, though if you only have time for one, they are listed in descending priority order.

Given how low it's time+energy requirements are, and how large the pay-off has been, I recommend Learning How to Learn by Dr. Barbara Oakley to everyone regardless.

I did Learning How To Learn twice and I still not sure how helpful it is. The only thing I found useful/applicable is spaced repetition.

What part of the course do you feel it's valuable? I don't mind going back to do it again.

A meaningful part of what I found useful was that I knew ~<10% of the content. It was 8 hours effort (Tuesday+Thursday 1 hour lunchtimes for four weeks, including all videos, quiz's, note taking (on the phone I was watching it on), and tests), and I'm now sure I know how to study effectively.

I think one working day is worth it to make sure you're up to date.

I also found the working memory, and memory information in general very informative and helpful.

The focused vs diffuse thinking part was very useful for me.
