Teaching my son to give a firm handshake
Took my boy to a networking event for work and noticed his handshake was weak. Looked unprepared and uncertain. We practiced that evening. Firm grip, eye contact, confident but not aggressive. He got it. Small thing but it speaks volumes about a man. Going to make sure all my kids know this before they head out into the world.
Good catch taking him to that event. Mine learned the same thing at a networking thing with me and he's been way more confident in those situations ever since. It's such a small thing but it matters.
