Elon Musk's secret to efficiency: Set deadlines with a 50% success rate and focus on solving bottlenecks. Musk says he usually sets deadlines at a level where there's only a 50% chance of completion—it's the most aggressive yet still achievable timeline. In schedules, there's a similar law to gas expansion, along with certain physical limits that constrain the speed of some things. So, create an aggressive timeline and always identify the current bottlenecks to help the team focus on solving them.
