Why aren't my chocolate chip cookies coming out the way I'd like them?
What you're describing is something that I'd consider normal in a cookie. Some cookies are more cake-like, some are chewy, some are crunchy, some are flatter than others - but they're all good. Almost any factor - from the type of fat, to the type of liquid, to the leavener, to the temperature of both the oven and the dough can affect the cookie's texture. I'd make two recommendations if you want your cookie less flat: 1) chill the dough for a few hours, or overnight. Then, form them and get them into the oven quickly, while the dough is stone cold. 2) Try a different recipe. Do a visual internet search for the type of cookie that you're after. Good recipes are hard to find, and sometimes you have to kiss a few frogs...
