The American education system trains us to make decisions based on knowing “all” the information. No one consistently gets A’s on tests after internalizing 70% of the material. You want to be 95%+ sure before committing to an answer.
In real life very few decisions are irreversible. It’s rare that you can’t move forward with 70% confidence, course-correcting on the way.
Most post-game analysis reveals the importance of gathering 40-70% of the insight needed before making a decision, but that there is little reason – and even adverse affects – for trying to acquire more than 70% certainty.
Paralysis by analysis can hold you back. You don’t have to be an A student in everything. Life isn’t pass/fail.
