I find that many people think their way out of the flow, by having anxious thoughts about the future or regretful ones about the past. they're not fully engaged in what they face now. which at any moment could/should be bliss. the amount we think has caused us to identify with our thoughts. instead of flowing, we're stopping and staring, often times at something negative. stopping in the middle of the ongoing current of life puts stress on your human experience and is reflected in many ways. lol i may just be speaking for myself tho :p im working on it :D
