I like reading BlackRain79 and watching his YouTube videos. Nothing beats experience though. Start playing without money for a long time first to learn the rules of the game. I actually downloaded a Game Boy emulator for iOS and the ROM for GBA World Poker Tour (2005). After playing that for a long time I finally got the basics like muscle memory of knowing what hand beats what and what possible combinations could be out there based on the board cards, stuff like that. Then from there if you live in a legalized state like I do you could start playing the lowest stakes online like .01/.02 NL.
