Explanation:

Please excuse my MS Paint.
Start by drawing a standard structure with carbon in the middle, as hydrogen can only form one bond.

The center carbon has too many bonds (maximum of 4), so we will shift two hydrogens over to the other carbon.
enter image source here
Now each carbon has too few bonds, so we will make a double bond between them.

This is the correct structure of C2H4, ethylene. The octet rule is kept.
