More people should meditate, it's good for so many things.
Sometimes people just need a break to release mental tension.
Meditation can also grant someone a good look at the situation, when you're calm and objective you can solve problems much better.
Other then that, it gives you discipline, which is required for Lucid dreaming.

I would really recommend it to many of you,
