When you're deep in worry, where is it coming from?
When you stop to consider it, worrying about the past (what has already happened) and the future (what might happen) are the culprits.
We get stuck on the
'I wish I'
The power is in the 'now' because it holds no worry. There is nothing to be anxious or stressed about in the present moment (the only thing that is real).
You are where you are now. Make the most of it.
P.S. My live workshop Back to the Present: Finding a Little More Peace & Calm in the Present Moment is today.
