I was really bad at soccer as a kid, because I was told "don't kick with your toes; that'll break them!" so then I kicked with the top of my foot, and when I was told not to do that either (because it would break my ankle, though they didn't give that as a reason) and that I specifically need to kick with the inside of my foot, I turned my leg 90 degrees and swung it forward, then complained about how I felt like my hp was going to dislocate.

Apparently you're supposed to rotate your entire body before kicking... but the coaches never said that so I didn't learn about it until a few days ago, when I explained my confusion to my brother.
