Do you ever feel like you are going and going and getting nowhere?
This guy was determined to get into the other side of his exhibit. Unknown to him, the zoo keepers had cleaned his pool and were in the process of refilling it. That side wouldn't have been safe for him. He was frustrated and just kept walking in and backing out... over and over again.
Perhaps your frustrating delay is for your own benefit too? Often only time will tell. So what do we do? I think we just do what we know to do and try not to "borrow" worries about tomorrow. Sometimes it just helps knowing you are not alone.
