Simple and easy

Can you guess why it is so hard to make your first million ?
The difficulty there is to make the sell even if this is at 1$ or $100000.
We don't have the skill to persuade people and make them believe they are in need for this product that we sell.
It is difficult to make a million in practice. In theory it is very simple and easy...
