This post reminded me of the song High Hopes. Here are some of the words:

"Next time you're found, with your chin on the ground
There a lot to be learned, so look around

Just what makes that little old ant
Think he'll move that rubber tree plant
Anyone knows an ant, can't
Move a rubber tree plant

But he's got high hopes, he's got high hopes
He's got high apple pie, in the sky hopes

So any time you're gettin' low
'Stead of lettin' go
Just remember that ant
Oops, there goes another rubber tree plant
Oops, there goes another rubber tree plant
Oops, there goes another rubber tree plant"

"Sticktoittiveness" is an important component of being successful. Though the obstacles may be extremely challenging, our perseverance can push us forward to new heights. Just smile and keep plugging along.
