What is your audio axiom?


So we all have been given audio advice and also shared with others our tips and advice. I ask you to share your #1 audio axiom. If you were giving advice or sharing experience (say to a young person starting in this hobby) what would it be? 
 

Here is mine (to start). “No matter how good your audio equipment or system, the quality of any given recording will make or break the listening experience”

Now the ball is handed to you guys…

90% of what you read on this forum or any audiophile forum is BS

10% value is better than the average for what mankind produces in general

@ozzy62 - it would seem that way, yeah? But in my apartment I've got a long livingroom and I have my gear set up width-wise, not length-wise, so on one side I've got about 15 feet until the window wall, and on the other side about 10 feet from the opening that leads to the front door. So while there are technically walls, they are far enough away so as not to affect the sound. 

The recording is 75% of the experience, the other half is mental - Yogi Berra 

Maybe these are not audiophile shibboleths but they work. 

Don’t call somebody’s baby ugly. 

Every time I find it, I loose it. 

Assume nothing!
