It'll probably take a couple of weeks for your fingers to callus, after that it's fine. Just keep it up! The trick to improving is just consistent deliberate practice. Practice every day, even if it's just 15 minutes. Take note of what you need to improve on, and practice those things. And don't be afraid to play things at very slow tempos at first, you want your muscle memory to remember how to play things properly. Start slow and build speed over time. A metronome can help a lot with this, and helps train your internal metronome at the same time, so I recommend that too. My #1 piece of advice though would be to not give up. I find the most frustrating and unrewarding part of learning an instrument is at the very start. You have to build your foundations from essentially nothing, you have 0 muscle memory built up, and progress can seem non-existent sometimes. But once you get through that initial phase, the sky's the limit! In my experience, it only takes a year or two to get good enough that people will enjoy your playing (provided you practice at a relatively consistent rate over that time). Have fun!
