To observe and watch one's own mind is something really interesting. The untrained mind will run and follow its old habit patterns. Because it has not been trained and taught, it will get lost in all kinds of stories and issues. Therefore we have to train our mind. The meditation practice in Buddhism is all about training one's own mind.
Ajahn ChahRemember you dont meditate to get anything, but to get rid of things. We do it, not with desire, but with letting go. If you want anything, you wont find it.
