7. Work on your handshake

No one wants to receive a "dead fish" handshake. Writing on LinkedIn, InfoShore cofounder Ashish Arora says that "a weak handshake equals a weak person" in most peoples' minds.

So how do you give a great handshake?

Arora breaks it down for us: "When squeezing your hand you want the grip to be tight enough to feel the bones of the other person’s hand lightly pressing into your skin and then keeping the same amount of pressure while you make two to three moderately strong shakes in the vertical plain. Maintain eye contact and a smile throughout."
