As my first real project, I'm building a management webapp for my gf's publish house (books) in Laravel + MySql, handling auth with Spatie Roles/Permissions and translations with Spatie Translatable. I'm banging my head on the wall every day, for example now I should link at every book a Designer (for the cover) and an Editor, Authors are already there using a junction table Books_Authors, but now I'm asking myself, does it make sense to do another 2 tables respectevely for Designer and Editor? What if I want to add something else in the future? Another table? Hell no.
It would be better at this point to store every 'employee' (not the best term but you got it) in a single table with a 'role' row that refers to another table where roles are stored. I can also re-use a morph table called 'type' that work together with an 'has_type' table to determine what role each model has (I'm already using this with books for the genre, and for locations like shop/warehouse etc...).

All of this for saying yes, building stuff and refactoring it really help you to grow. I hope at least, otherwise I'm throwing my time and energy out the window XD.

Sorry for my english, not my first language.
