Yeah, that's meditation. There are so many types of meditation, there's almost certainly something that will work for everyone. As long as you're focusing inward, not really trying to be cognizant of the things running through your head, it achieves the goal.

Personally, I like fixed point gazing, which is exactly how it sounds. Find something, stare at it. Resist urges to blink or look away. Eventually your eyes will water, you'll start to get bored... Keep going until you just feel like stopping.

I've heard of some meditation for people with ADHD, where their mind is always trying to run. Go, sit in a crowded place like a food court, and try to listen to every individual sound. Not like, conversations and their meanings or anything, just the sounds of the words. Eventually their overactive mind will just start to wear itself out.

My point is, there's no one "meditation" - as long as you're setting the time aside to focus on self reflection, you're doing it right.
