Hey I would Like to add my personal experience her just remember one thing: Learning an instrument is never going to be easy

. It takes a lot of time and effort to memorize chords (even for just one song) and figure out strumming and everything. If you get frustrated, give it a break and pick it up again later. It won't be easy or quick, so don't expect it to be. If you are having a very difficult time, a few lessons with a private teacher can get you on the right track.
