I saw this today and it rings true:

When you stand still, you reject the struggle, and you refuse to change and grow. Ultimately, you reject fulfillment, happiness, the dance for joy and everything else that is eternally good.

– Matthew Kelly, classical actor and game show host

And no, I had no idea who he was either without googling 😛

And this is a matching quote:

Fight the good fight every moment, it’s your only way.

– Triumph
