Yep keep it out the fridge for an hour before cooking as suggested,
oil the steak, not the pan as suggested,
Get the pan proper hot - as suggested,
sear both sides for about a minute each - yes you guessed it, as suggested,
Press your index finger against your thumb, and feel the pad of your hand. This is medium/rare, thumb and middle finger is medium, thumb and ring finger medium/well, thumb and little finger is well done.
Obviously depends on girth

of the steak to determine how long to cook it, but the firmness of it using the above rule will produce the outcome that you desire.
Enjoy!!
Oh and friday night is fish night!, saturday is steak night!!!!
