I am currently working through two self-paced courses
And reading two books.
Predictably Irrational by Dan Ariely
The Little Black Book of Training Wisdom by Dan Cleather
I’d say total time learning is no greater than three hours a week, one chapter a week on the books, and one section of self-paced learning.
Blogs, book notes, and leadership directives help me play with the ideas I’m working with.
I don’t think it matters how you do it, but it’s nice to make the time to do it.
