Tattoos? Piercings? Sounds like you watch too many "top 5 things alpha males do" videos on Youtube. I work a white-collar financial services job in NYC, let me tell you, you show up to the interview with tats and piercings, you're not getting the job. McDonald's always needs dishwashers though.
Or, you can play your guitar at happy hour for tips. Don't worry, NYC's housing courts let you live rent free for up to a year before the marshal shows up and throws your tatted a$$ out on the street along with your guitar.
Here are some real DHV's:
Dress well. Not expensively, but well. There's a difference. Being dressed in fitted clothing of the current fashion demonstrates high social IQ.
Have a sense of humor. Be warm, witty, charming, and make people feel comfortable and wanted.
Call out bullsh!t.
Work out and be in shape.
Maintain a good haircut.
Sure, being tall, handsome, and wealthy all help.
