Most Helpful Guy
Here is what i did.
Fix your posture, Walk with your head angled slightly above parallel, Put power behind your voice.
Posture: It's Psychological, Healthy, helps brain function
Head Above Parallel: Pseudo Powerful look.
Voice power: Know what your talking about, and instead of using the weak tones most people use, have emphasis and know what you're talking about.
Doing these things, Will make you look 1000% Better than almost any Beta-Male. You don't need to be strong physically (Although it helps.) but mentally, it's all core.
The core behind Male strength is in the simple strong word choices. Have 2-3 back up plans, and topics.
