Some days it really pays off immediately to do yoga, like when you get a good pop like that. :)
Other days are like day 3, even for me and I've been meditating for years. Sometimes you just "go through the motions" but even then, it still helps. It still changes your inner-workings, the practical functions of your body and mind still respond, even when you don't "feel it". Just stick to it the best you can!
If you want to try out meditation, I think guided meditations are a great way to start. I'd suggest the 10 minute one from Sam Harris here:

As I personally like his voice, respect him as a neuro-scientist/Buddhist, and 10 minutes is a perfect length of time. Fit it in on a break at work, between classes, whatever, you know?
UCLA has some free ones as well, although I haven't reviewed them yet:

Feel free to come back and ask any questions! Meditation can be a little weird at first (turning the mind back onto itself. Aware of your own awareness. Concentrating on your own concentration. You'll see!).
Namaste!
