Yeah, I've listened to the Success one every day for a week (usually right after I wake up). It definitely helps me set the tone and not get hung up on the things that usually distract me.

The way i figure, i more than make up the time that I spent listening by getting through my day with a little more ease.

I've yet to really try out the relationship, health ones. The spiritual one is decent, but the song on the success one is by far my favorite.
