Next issue, how to get the most out of the effort. The majority of books will not help you retrieve that elusive bit of information that would be so helpful if you could only find it! So, having learned the hard way, I make notes in an app my smartphone. I let my associations trigger my notes. What feels most important to remember, what has relevance for one of my projects, what do I want to further investigate. And, last but not least, how do I implement my learning, what will be my ‘next action’. And that is where the return on my investment starts.
