An easy smile.
A firm handshake.
And an easy laugh.
(All of them sincere.)
Put them together, and they’re a formidable combination.
Make them yours.
They will open doors in your career, business (and love!) that nothing else will.
They allow you to start the match one goal up.
You have to really screw up to screw it up. (Hint: Screw-ups are usually reversible.)
In short: Be someone who’s instantly likeable.
