Thanks for contributing. You’re welcome to jump in on my posts/advice anytime. I appreciate anyone who keeps me technically honest.
I am all for being patient, TT you are my inspiration, but seriously roadkill, if you don’t plan on staying a “plate racker” for the rest of your career in the gym industry start reading up.
You happen to be on a site that offers a TON of great free information.
A simple search provided me with the answers you sought for.
If you want to make a good living off of this game start reading all the back issues (yes all) and carry on from there. If you search for “feed your head” you will get great suggestions on reading material from the writers on this mag.
Oh btw if you want to be great get under the bar too 
Good luck with your application
