I would consider myself humble
Usually its the ones who dont got alot to offer who brag and boast I remember a quote i heard from a movie it goes
"the loudest one in the room is the weakest one"
Now if u think about it You can be loud by bragging about your financial status or by buying luxury goods that make you stand out. If I started driving around a Ferrari, all that it will do is cause more people to snoop into my business and try to compete with me. Also, playing it quiet has three benefits: more cash, respect and a clear path with a clear path you know what you can afford and you dont go buying stuff you dont need.
