The mistakes were having no budget to do the project, doing it piecemeal, starting in the middle of nowhere and going to the middle of nowhere: a recipe for disaster. In the case of the England project, the mistake was to have land acquisition processes that weren't standardized enough, which meant construction was carried out without a defined framework for land acquisition. That meant that construction would begin but have to stop, resulting in delays and drastic increases in costs.
The universal recipe for success is to take our time to get started and to do our homework before making promises. Once the project is well defined, announcements are made and things speed up. We don't do the opposite. We don't speed up too quickly. We take our time at the beginning. We'll move faster tomorrow.
