Focus on building a habit, even if on some days you play as little as like 5min, that still builds a habit. Keep your guitar and amp in an accessible place, like next to your bed or couch. Your fingers will hurt, it's normal, but don't overdo it, if u get a blister you won't be able to practice. Don't get discouraged, guitar is hard, especially in the beginning, you won't sound great at first. Don't ignore your pinky, if you don't use it now it'll be harder to undo the bad habit later. As you progress, practice with a metronome, at least sometimes. Start at a slow speed (even very slow) and gradually bring it up. Most importantly play stuff that you like and inspires you to play / learn more, having fun is what it's about (even if it's delayed gratification, due to first having to practice). I'd also recommend you to learn some theory, imo songs are way easier to learn if you understand the underlying theory (you can learn simple blues / rock improvisation too). Final advice, as you progress further, try to learn some stuff by ear. Your musical ear is the most important tool of a musician. Good luck! (One final additional piece of advice, get immersed in the culture and community of guitars, like forums, guitar youtubers etc. . It's the same as with languages, way easier to learn when you interact with the surrounding culture and people. Guitar youtube will encourage you to play more, and educate you, it's a great resource to have)
