My body taught me the necessity to relax , even for a while.
There were a few mad years of two jobs, house, family, until I fell over at a street rushing from work to make it to the butcher's shop. That was the first wake up call.
Then some more madness, I fell from the doorstairs, broke my foot. That was a stronger call.
Then finally, through some gradual changes in easing the work schedule,job change, and a strained ischiaticus I realized, I do need relaxing periods, and "me-time".
So what I do now is, mostly, do then relax for a while, then do again, relax etc.

Relax is rarely completely without either music, news, videos or planning, at least the body rests.
But at extreme times, I will shut off any stimuli and just ride the train or walk the streets to sort of silence the brain fireworks...
For anxiety I use the box technique breathing.
I should go back to meditating though, as we did in yoga. It is a deeper mindfullness that does good.
I can't meditate to save my life. My brain isn't capable of shutting up -- well, almost. For me, the ultimate mind-cleaner was taking my SeaDoo to the lake on a weekday afternoon. On the weekends, the lake was crowded, but on a Wednesday afternoon, I practically had the whole lake to myself. Me and 110 HP of Rotax would go full throttle the whole length of the lake -- about 60MPH on smooth water. That is the most "in the moment" I believe I have ever been.
