Hello @knowledgefruit,
this year 2020 was a lot of learning in all aspects.
I think that unlearning is simply "learning a new technique" or "acquiring a new style to do things", it is really necessary because we are living in times of constant change and we must optimize the time, make the best of the circumstances and above all things give more value to our environment.

Great reflection shows us your post.

Happy New year..!
