Anyone can learn, the main desire. Start with simple chords, Am, C,E, etc. Buy ion new strings, they are very soft and do not cut your fingertips. Remember the location of your fingers on each chord, develop your hand memory and everything will work out. The most difficult stage is filling the battle, but it is not difficult here either. Hold all the strings without pressing them to the neck, the sound should be muffled and look for a rhythm with the help of a hand movement "up", "down". Personally, I find it more interesting to play by sheet music, there are more opportunities to choose your favorite music in different versions. Well, actually, there is nothing more to add, if it does not work, then you should turn to the guitar tab and this should help you!
