I've seen some people doing :"faking it till you make it" as you emphasized in your post, but some of them are only for a show they spent lots of money in the clothes they are wearing, they spent expensive cars just to show to their friends that they are rich; but they struggle to pay their bills at home, then they ended up selling their lambo, and ended up selling their house because there was a money emergency that they have to pay. We have to think first before buying things that we don't need to buy expensive stuff just to impress our friends because in the end we are the one who are responsible to our future.
