The Confidence Problem
Overconfidence kills capital. Underconfidence leaves money on the table. The skill is calibrating confidence accurately. Professional allocators know what they know and know what they don't. They bet big on areas of deep knowledge and pass on everything else.
Honest Assessment
Can you predict cash flows? Have you done this before? Do you have competitive advantage in evaluation? If yes to all three, bet appropriately. If no to any, pass. Most failures come from betting outside circles of confidence.
The Circle of Competence
Know your circle precisely. Expand it slowly through learning. Bet appropriately in your circle. Pass ruthlessly outside your circle. This is not limiting. This is the path to explosive wealth creation within your sphere of mastery.
Know yourself. Bet accordingly.
