A pebble thrown in a pool
may ripple from end to end,
but tossed into the sea,
it is swallowed by enormity.

You want to be the pebble in the pond that creates the ripple for change.

I am a waning bird
encased in a glass sphere;
I cannot see my prison,
and my cries no one can hear.

The winged beasts and angels know, that mortals cannot fly.
But how I flew to see the sun; a broken bird am I.

Have a ripple effect

Everything we do, even the slightest thing we do, can have a ripple effect and repercussions that emanate. If you throw a pebble into the water on one side of the ocean, it can create a tidal wave on the other side.
