Going great so far with the rhythm and the changes, just need to get used to stretching the fingers from 2nd to 5th fret its exhausting when playing for a longer period
It'll get easier, I promise! You can always hop between the 2nd and 5th sometimes, you don't always have to leave the first finger down. (Or mix it up with just going to the 4th for a while, give yourself a bit of a break. 😉 )
