Whenever I meet another guy, I always make sure that my handshake is firm and assertive, just like my dad taught me. Most men were raised to give a firm handshake when meeting someone. A firm handshake means that you're a "man," and that you mean what you say and stand for something. A firm handshake gains immediate respect, while a limp hand places you in a submissive position. Now, a firm handshake may mean more than that.
