C++: How to get a std::list

Given a std:: list

std::list< int > myList

and one element in that list

myElement

How can I get an std::list::iterator to that element efficiently?

A slow yet working example is

const_iterator it
for( it = myList.begin(); it != &myElement; ++it)
{
    // do nothing, for loop terminates if "it" points to "myElem"
}

Is there a quicker way? like

const_iterator it = magicToIteratorConverter( myList, myElem )
