It's not a flaw, it's a feature.
Thousands of years ago, spotting what could go wrong kept you alive. That wiring didn't go anywhere. Your brain still scans for threats and problems faster than it finds opportunities.
Most goal-setting fights that. This one uses it.
Write down everything that would guarantee you fail at your goal. Your brain will fill that list fast. Then flip it. What you've got is a clear, practical roadmap built around how your brain actually operates.
Everything gets easier from there.
