Its indeed very hard to let people believe in the bitcoin
Open yourself a shop, and show, how it work, positively.
It is actually not so easy to make a shop and accept bitcoins for it as a payment... because maybe people around you are still not aware of it and making them know about it would take some time... first someone should try to do some survey in the town to know the interests of different kind of people and if you really find it in their interests then go for it...
But if he provide all of those products which are all imported and all of them are unique and amazing for the community around him then people will like to buy that things and for that they will learn about bitcoin and will start to buy things from him with bitcoin.
