Wherever you want to fit in, you have to become one of that circle. Don't think too highly of yourself. Never mention that you own a Maserati, even if you have an Aston Martin, you need to be low-key. If all your colleagues ride their 28-inch bikes to work, then you'd better walk to work and show off your canvas bag, complaining how poor you are. Only in this way can you keep the mental balance of the masses.
