I don't recommend too many Career books but this is a major exception. If you want as much detail as possible, as much understanding and clarity as you'll find anywhere, this is the read for you. Click on the following link to find the Book at Amazon.
What Color Is Your Parachute 2018 by Richard N. Bolles*
(*Sadly, Bolles died in 2017 but this was completed before his death. Not sure if anyone will take up the task and continue to flow. These books have been published since around 1970.)
