I'm exhausted at the moment. Davening is about to begin and I'm falling asleep.
As I walked in, and wondered how I was going to daven well, I remembered something R' Shimshon Pinkus writes in his sefer in tefillah.
Simcha. For one to truly daven, he must have complete simcha about davening. How can you not? You're about to have the opportunity to daven in front of Hashem!
Mincha now. Time to daven. Simcha!
