"I can't wait"

While I find myself using this phrase a good deal when associated with feelings of excitement, it makes no sense to me whatsoever.

"I'm excited" makes sense.

But "I can't wait" ?

What do you mean you can't wait? As in you're not going to make it until what you're waiting for comes? You're going to die of anticipation? Not likely.

It's a phrase I'm trying to weed out of my brain. Because I *can* wait, by God's grace. That doesn't mean it's *easy* to wait. But I can.

And for some things, I'll wait for as long as I have to...
