You know you are a machine head when being in the fairway is no longer an issue.

Planning Ahead
 

Or when you ask on a 487-yard par 4...

"Where's the flag?"

You pray that the elevator is empty so you can check your impact alignments in the mirror

You wave at people with a RFP

You shut doors with a bent right wrist and the thrust of PP3 against the door knob

Educated Hands
 

All of your friends give you the "Secret Hand Shake", because they know you will give it to them don't give it to you.

When you're thinking maximum lag pressure on your snow shovel.
