Just CLOSE your eyes, RELAX your body, QUIET your mind...
And take some long, even, slow breaths. This is "Meditation".
Not as easy as it sounds, I know.
But, listen up: after my body told me to piss off recently and stopped functioning properly (ie. I got can't-work-for-five-days level of sick because I wasn't shutting off my brain enough to stop the mental chatter which would allow me to stop stressing and sleep properly), last week I started meditating.
For as little as 5-10 minutes after waking in the morning, and in my bed at night to put myself to sleep.
THE RESULT? A more focused & efficient day, less stressing about money, more trust in how things were unfolding, and a proper rested sleep.
Try it, even for just a 2-3 days, and take notice as to how your day might differ from the ones where you did not make a conscious effort to still your body and quiet your mind. What have you got to lose? You won't lose sleep, trust me.
