Cooking Rut

I'm usually a decent cook. I mean, I can follow a recipe. However.

I have now failed 2 recipes in a row. 2 of 'em.

First, I tried to make these homemade oreos. They just didn't work. I made the dough, let it chill for the right amount of time, and for the life of me, the dough wouldn't roll out right. So disappointing.

Then I made these yesterday. These biscuits are my standby! They are cheesy, fluffy, and delicious! This time, they were tough and salty and just plain ol' nasty. 

What is happening to me? I just need a recipe to work, folks. Just one. Here's hoping to a better culinary week than my last weekend!
