Ten years ago I was working in an office. The job was pretty challenging. Lots of things would come up and need to be dealt with quickly. And many many things popped up simply to make the task at hand even more difficult than it began. A coworker and I started soothing each other with this phrase, "Be water." We meant it as a reminder to flow around or over the obstacle, NOT to try to push through it. Keep moving, keep flowing, keep progressing. Ten years later, I can add something to the list of positive qualities of flowing water: persistence.
Flow. Allow. Breathe. Accept. Act.
You might bump into a rock now and then, but if you just allow yourself to flow around it, you'll keep your forward progression.
Maybe I should have been a swimmer.
