This is not a sock 2

This is not a sock. This is a piano!

Life is like a piano. 

There are black and white keys; 

there are up and down. 

It all depends on what you want to play.

This is not a sock. This is a line of footprints.

An idiom from Hokkien, literally "a grass with a drop of dew". It means something like there's a will, there's way. So, don't give up, bring your faith, your smile and His blessing along with you. 

Reminds me of the poem "The Road not Taken" by Robert Frost. 

"...Two roads diverged in a wood, and I—
I took the one less traveled by,
And that has made all the difference. "

有句福建話叫“一枝草，一點露。”
意思是，天無絕人之路。
今天，這不是襪子，這是腳印。路是人走出來的。帶著信念，帶著微笑，帶著祂的祝福，走下去。

This is not a sock. This is a butterfly. 
Don't look down on yourself. 
Who knows you may be the one that cause the butterfly effect. 
Start thinking positive by today. 
Read the book the Secret by Rhonda Bryne and you will know.
Keep praying. Think good, do good and learn. That's what I always tell myself.
