Do what you wish, but don’t do it because you’re scared. You must own your actions in life.
Do what you wish /Do what you wish to /Do what you wish to do 该如何说？
Do what you wish /Do what you wish to /Do what you wish to do
以上三种都正确。实质最容易见到的是第一种。
这就是《剑桥语法》所说的所谓自由选择结构free choice construction.
Do what you want/like/wish/please.
这种结构中， what=whatever.
please不可后接to.
