have to be creative loh
come out with a product in need and no one is selling yet
just like the smart phone. they are all in one
meaning u can use it to surf web, make phone call, take picture,
play game and run apps
follow the idea and come out with a all in one product for
kitchen
all in one set, meaning it can use as washing machine, a fridge,
can cook and etc
as for transportation beside designing new cars and trains
maybe u can design a flying suit and sell it for money
