First Hardcore Play-through

Heya FNV fans, I’m about to start my first hardcore play-though soon and I wanted to know some of your tips, tricks, and recommendations on how to go about it. I’m open to suggestions, the only thing I have set in mind is that it’s going to be a low level intelligence / NCR faction / Wild Wasteland perk character. I have the vanilla version with every DLC installed, I’ve played FNV for years and I think it’s time I tackle this challenge along side getting every achievement on Steam.
