Assumption examples:
“I think people will like it.”
“I feel this price is correct.”
“My friend said it will work.”
Congratulations.
You are gambling.
Better approach:
Replace “I think” with
“What data proves this?”
Small tests beat big opinions.
Example:
Instead of launching 10 designs →
Launch 2 designs →
See which sells →
Scale winner.
Habit:
Test small.
Decide later.
