Prepare for cringe (noob questions)

Alright so note, I have never made, seen, or tasted DIY ejuice. I'm a pretty avid vaper and as you can imagine spend a LOT of money on juice. I have a lot of knowledge of all things vaping aside from actually making the juice. I really want to get into making my own juice! I just have no idea where to start, where to buy the ingredients, where to compare different brands, what to look for when looking at ingredients, what the different acronyms for juices mean, or what to even add into juice to make flavors. I'm probably going to watch a bunch of videos on DIY juice later tonight but I know all you handsome motherfuckers can be very helpful and not just raging douche weeds that hate on beginners xD thanks!
