Hi simpleman9,

Don't give up! G and D are pretty tough to get down. Remember, when you practicing switching between these two chords, you have to do so slowly, to build that muscle memory. Do it as slow as possible, and what you want is to get your fingers on the right spots.

Do this and then speed it up slowly.
