Narrow It Down
Interpret each energizer however you feel like. Narrow or broaden it. For example, "What could you do to help people think critically?" could turn into "What could you do to help [specific type of person] think critically about [specific thing]?"
I've purposely made some questions broad so it can allow for more freedom and creativity.
Feel Free to Skip
Skip energizers you know for sure you can't do. For example, you can't carve an apple if you don't have one.
On the other hand, you probably shouldn't create some random excuse to get out of an activity. Even if you're not a designer, you can still design things. (It won't be perfect, but it'll be decent.) Don't let that stop you from being creative and trying out something new.
Don't Be Afraid
No one is going to know if you "mess up" on an energizer. Truth be told, I don't even know if it's possible to "fail" one of them. It's about the process, not the end.
