You can never learn Sales by reading books and watching videos, you can only get motivated by that.. To learn Sales (telesales) dial 300+ calls daily and (direct field sales) meet at-least 5 clients daily...Only customers can teach u sales!

Sell (service or product) as if you are buying it, convince yourself first that, it is worth buying..It is very simple; u 'cannot' convince someone till the time you're not convinced
