There are a lot of marathons, but there aren’t many sprints. Making a profit is a marathon that involves getting enough exposure. The exposure leads to the profit, but too many people just want the profit right away.
The profit does not lead to the exposure. There will be some points where you will have to spend money in order to get the exposure. Getting the exposure will lead to more sales which in turn will lead to a bigger profit.
Don’t focus on finding the profit. Focus on finding the exposure that will lead to a profit.
