Once upon a time there were two rabbits. Rupert and Rectangle. They were hanging out, doing rabbit stuff. Looking for carrots, finding turtles to race, and resting from making more rabbits, as it was their day off. Rupert, the younger rabbit, decided he wanted to make a model volcano. Kind of like Peter Brady, only without the electricity. Most rabbit experts will tell you that rabbits generally don’t use electricity.
So this young rabbit was building this volcano, but he couldn’t quite get it to work right. He didn’t have the lava mix quite down. I think he was using a combination of egg whites and mulch, or perhaps some kind of gelatin derivative. He kept getting really frustrated, and he was about to give up. The wise older rabbit, Rectangle, said “Don’t give up yet, Rupert!” But Rupert just threw down his volcano making tools in dismay.
“Nothing is going right. I want to do this, and instead it does that. I want to make it lean right, and it wants to lean left.”
“Relax, Rupert relax. Go with the flow. Don’t fight against the natural order of things. It will come in time. It always does. Just remember to do things one step at a time. If it doesn’t go the way you want it, change what you are doing. Step back, take a bigger look, and figure out what to try next. It’s only practice, after all.”
Poor ruper was following along, but he didn’t quite understand the last part. “Practice? Practice for what?”
“Why tomorrow, of course. Everything you do today, is just practice for tomorrow. Because if you allow yourself to release your expectations, and let things be just the way they are, you’ll be fine. As long as you learn from what happens, you can do it better next time. Especially because you always have tomorrow to look forward to, right?”
“I guess so,” Rupert replied, “But how will I ever finish, if I only practice?”
“Take a look around you young sir, take a look at everything. Does everything look finished to you? Are all your friends not still growing? Are all the trees not still getting bigger? Does father not upgrade and improve your rabbit hole every winter? Do you not need to learn new things in school every year? Does your Uncle, the carrot farmer, not have to learn new carrot planting methods every year? Practice. It’s all just practice.”
 “Practice for tomorrow. I got it,” Rupert said, getting back to work on his volcano.
“And one of the best parts about realizing that everything is practice for tomorrow, is that no matter how bad you mess up or how well you do, you can always look forward to being able to get better.”
And Rupert proceeded to make the best volcano ever.
