F is for flexible. Not my body. It's not very flexible at all!
But personality - you bet! I'm good at "going with the flow". Remember the Slinky? It went from side to side, shifting and changing when it needed to so that it could either balance or go all the way back to it's original shape.
When I was teaching the catch phrase of the day was "monitor and adjust." And it meant just that - if something you were doing wasn't working, you switched gears and did something else. You tried different things until you hit on the one that worked with the kids you were teaching. I learned a lot from that....I learned to do the same thing in life. I learned that if you keep on doing what you always did you will keep on getting what you always got. Read that somewhere - and it's true. If you're flexible you can take advantage of opportunities that pop up, you cease to be rigid and you learn to bend without breaking.
Being flexible is said much better than I could ever say it in Ecclesiastes 3 - To every thing there is a season, and a time to every purpose under Heaven. Embrace your season. That's being flexible.
