So hypothetically I have a friend who wants to get a job in cyber security but has no formal education or means to afford one, at the moment. He knows enough about computers to navigate and execute most common tasks, and certainly has the drive, common sense, and brains to succeed but can't afford to in this almost cutthroat field...
How would he begin to teach himself?
He has a laptop, Kali Linux, The BTFM and RTFM books, The Hacker's Playbook 3; and the internet.

Make his day with your two cents.
