I actually meditate basically all the time. At one point I thought, why not have the clear crystal ball all the time, instead of "just" when I make time to sit down and meditate?
Pretty much the same here. I meditate when I get stressed, I do yoga moves every day. It helped me tremendously getting my life back together so I keep at it.
For any onlookers: this is a process so start at any point, no minimum requirement to be valid. :)
With all the time I actually mean all the time, dunno if you mean the same thing. Like I don't do any actual yoga exercises or meditation sessions, I simply meditate while making myself some food, for example.
But yes, it's definitely a process that you can do ass little or as much of as you'd like :)
I used to do it while trying to sleep, while being alone, while doing anything that needed my attention but my head was too messed up to stay calm. So I meditated, counted breaths, observed thoughts and feelings, turned inward as much as I could. Since then stuff has gotten better and by now I only meditate if things get rough.
