Well... almost anything. And you may have to try it two or three times to be sure.
Really, if you're not trying something new you're severely limiting yourself in life, work, ministry and more.
Unless of course, it's something you shouldn't try at all. Those things are out there. Don't try them.
But if it is something you should try, you might need to do it more than once to see if it's a good fit.
Obvious? Well then, what have you tried lately? What have you tried that you shouldn't have? What have you tried that you should do again?
