A sale is a transaction of value between two parties.
The party that believes that the value they are offering is more than what they are getting in return has an upper hand in the transaction.
To develop such a belief, whatever you plan to sell, you’ve got to sell it to yourself. Unless you do that you’ll find selling hard.
Once you’ve sold it to yourself i.e. you’ve realized the value of what you are selling, you will know that the price you are charging is too low for the value you are offering.
This understanding takes all the fear and doubt that comes in the way of selling.
And, makes selling a breeze.
