Hey, so I'm teaching myself how to play guitar. I have a traveler guitar, which makes it easy to whip out and play anytime, and the Gilb Classical That I dumpstered. (I call it Darwin. The little guy is Nemo.)

Was so psyched to get that on sale. Anyway, the advice I have is to look into P4 Tuning. Instead of EADGBE tuning, it's EADGCF tuning. Look up stanley jordan, or alex hutchings on youtube. Another guy who talks about P4 tuning is Tom, from "Tom's Music Lessons" on Youtube.
Why? you might ask. It's because I had to know about music. I got really frustrated trying to learn guitar. It's like, for every other instrument in the world, (violin, piano, electric harpischord, you name it) students are taught about music theory first, and then how to apply that to the instrument they are learning about. With guitar it's mostly backwards. The videos are all like "This is a super advanced lesson! We're gonna learn about the circle of 4ths!" or "This is for advanced guitar players only....its INTERVALS! Reading SHEET MUSIC! *(cue the movie announcer voice of DOOOOM)*
...which, yeah, was fucking frustrating. In P4 tuning, you learn one shape, and it applies for the whole fretboard. A major triad will always have the same shape, no matter what root note you have.
If the excess of info on "standard" (spanish) tuning versus the minimal amount of info on P4 tuning gets you hung up, then my advice is to learn music theory. Learn about whole notes, half notes, timing, the major scale, minor scale(s), etc, etc, etc. And don't give up! I've been at it for two years, and it get's way easier with time.
good luck.
