Grades of reference

Study of Ed Corney in the encyclopedia
 of bodybuilding.

Wow! If I was to be reductionist to help you not fall into the trap of this How-to industrial complex. It's to simply use reference for your own goals, all to get help with your work. Then auto-regulate accordingly!

Tiers of reference.

• Better spec Tier: One that speaks to your autonomy and personal projects. Making you accomplish what it's for and who's it for clearly. (Example: What you and the client want.)
  
• Okay spec Tier: Muddier in intent. Less closer and could only be partially used. (Example: Obscure searches online where the idea is in the rough.)
  
• Be Careful Tier: More of a time sink, makes one pass the time rather than spend it. An overload of inspiration with knocking productivity out of balance. (Example: Playing too many video games. )
• Whoopsie Tier: A copyright strike and, when used, makes you look like a hack. (Example: Tracing over other people's artwork then claiming it's your original, merely serviceable.)
