Used to take me almost half an hour to meditate, but after a while I shaved it down to 10 or minutes. Put my back up against a wall while sitting on the ground, and just stop thinking for a while. Better than a nap 'cause it doesn't produce much melatonin (sleep hormone), which can screw up your sleep schedule.

I meditate all the time, brah. It's so damn relaxing, and I get to submerge into the new albums I get.
