Are we waiting or waiting?

Let's talk about waiting, specifically waiting on the Lord, as in everyone's favorite verse.

But those who wait upon God get fresh strength. They spread their wings and soar like eagles, They run and don't get tired, they walk and don't lag behind. Isaiah 40:31 (The Message)

Now, I had for a very long time understood this verse to mean that when things get hard, just sit back and wait, and God will give me strength.  I don't know that this is a bad understanding, but I don't think it's the best.
We need to really stop and look at the word "wait".  I hear that word and my mind immediately goes to "Waiting for Godot."  The whole play is about 2 men waiting for a 3rd, named Godot.  The script revolves around them sitting, and waiting.  They do not go on to anything else, they do not try anything else.  They have put all hope in help from Godot, so they do nothing but sit and wait for Godot.  Now, many of us a Christ-followers do this, and I think it can be a good thing.  Jesus is the vine (we've talked about this) and our life and help come from Him.  Sometimes we need to wait in this context.
But there is another definition of waiting.  The roots of the word "wait" are the same roots as the words "waiting," "waitor," and "waitress."  Now, a waiter does anything but wait in our first context.  A waiter is constantly going, always on his feet, continually serving the master.  What if we use this context in Isaiah? 

But those who continually serve God and work to meet His desires get fresh strength. They spread their wings and soar like eagles, They run and don't get tired, they walk and don't lag behind.

That now means something completely different.  Instead of sitting and doing nothing until God gives us the strength to continue, we now press into Him.  We work at His side, we strive to meet His every desire and serve Him for as long as He would have us.  And, in that serving or waiting if you will, He renews our strength.  We will soar like the eagles as we wait upon Him.  It makes me want to work and serve.  How about you?
