The Power of Process
Good outcomes can be luck. Good process is a skill.
We often judge decisions based on their outcomes, but a good outcome doesn't always mean it was a good decision. The world is random. A great process, however, is repeatable. It increases your odds of success over time. Decision Log is built to help you create that process.
