Path to OSCP?

Well long story short:
In IT for about 15 years (network, admin, security, vulnerability scanning etc).
CISSP, CEH, SEC+ and only know very limited Python and pretty fluid with Linux and Kali.
My next life goal is OSCP. I need to further understand security and think this is the path I would like.
Does anyone have a tried and proven formula that helped them pass ie:specific classes or research
For now I'm studying Kali Linux unleashed followed by the free metasploit course they offer. I see alot of penetrating courses on udemy and cybrary but not sure what is relevant or not.

Other things you can do to prepare is use HackTheBox and use ippsec walkthrough's (on youtube) to go through some of the easier boxes. There are also some VulnHub machines that may be good to do beforehand. Just googled "OSCP Hack the Box machines" or "OSCP Vulnhub Machines", people have lists of machines that are somewhat related to what you'll see in the labs.
Good luck.
