Thru your body language. That does the majority of the talking for you and you can't fake that.
Body language is big. How you carry yourself is very important, but you CAN NOT fake it. Stand up straight, good posture, shoulders back. Walk with confidence.... take big steps, always look in the direction you are going and never look at your feet. Make eye contact.... smile.
Be in good shape, which means you have to work out.
Wear clothes you like and that fit you and you are comfortable in without looking sloppy. If you are comfortable in suits, these are the best... but if you don't like wearing suits... don't do it because your body language will reflect your mood.
Never get drunk... it's okay to have a couple of drinks but alcohol makes you stupid.
Put away your FVCKING smart phone... seriously never take that sh1t out unless you are making a call... if someone texts you and you MUST look at it like a trained monkey... excuse yourself and do it isn't private. Your life is what is around you... not in your godd@mn phone.
Last but not least, never chase women. Offer dates, ask for phone numbers, make an effort but if she declines, forget her... men that keep trying and trying chasing one woman is pathetic. And it totally fvcks up your mindset.
