I believe successful sales people put forth that extra 
effort that turns potential clients into first time 
customers.  Sales people who attend to the details by doing 
whatever it takes to win over a prospective customer 
distinguish themselves from the countless others who don’t 
put in any extra effort.

A successful sales person is the one who can sell shoe in a 
place where noone wear shoe.

A successful sales person is the one who can sell shoe in a 
place where  every one wear shoe.

Person who has good communication skills, uses extra effort 
to convince his customers and is able to achieve his 
target. A successful person is one who can sell comb where 
everyone is bald.

the two most important things which makes a successful sales
person are,
1.communication skill
2.complete knowledge about the product
