FINALLY chocolate chip cookies

I don't know what my problem is, but I have not been able to make good chocolate chip cookies...ever.  Seriously, they are always too flat or too hard or too disgusting.  I found this recipe on pinterest and FINALLY they worked out.  Jack came home from being on overnight call and the first thing he said was, "Oh, you learned how to make cookies!"  So here is the recipe, I have to post it here so I don't lose it!
