The Ultimate Workflow and Structure for Rekordbox? Please share!

Hi fellow DJs! 

I'm doing some research to try to find "The Ultimate Workflow and Structure" for Djing with Rekordbox and would love to hear how everyone is doing it! 

What kind of DJ are you? 
Wedding or club DJ, power mixing with cue-points everywhere or keep it simple. What kind of hardware are you using. 

How is your music collection structured today? 
A playlist per gig, genre, key, purchase, all of them? intelligent lists and/or regular? 

What is your (dream) workflow? 
From buying, adding, sorting, finding, exporting and playing. 

What is good or bad in your current system? 
Long term and short term. 

@Pulse Cool now or is my question "data collection"?
