Before you finish your new idea or launch your new project, it's worth taking a few minutes to realize that two costs are dramatically underestimated:
1. The cost of selling. How much will it cost you to sell this to an agency, a nation, a customer? How much will it cost them to sell it to the next user?
2. The cost of maintenance. How much will it cost you to stick this project out until it pays for itself? How much will it cost your users to maintain this idea over its useful life?
Hint: It took a decade to sell most people on the personal computer. And the cost of a PC out of the box is less than 1/6th of what it costs to keep it running and in use over its life…
