Hello everyone, I am a 48 yo man who purchased an acoustic guitar a month ago. I have always been an air guitarist/ wannabe. I really want to learn how to play , I have watched about 50 vids on guitar tricks so for. Man is it hard to get my old fingers to do what my brain wants them to do. Im having particular trouble with the spider exercises, is there a trick I'm missing or just keep practicing?

Thanks for the input!
