The two most important abilities in investment:

One is to have the fortitude to hold cash and not move it until a perfect exit opportunity appears

The other is to be able to hold the position for a long time and survive the darkness until the valuation of the target held is repaired or even the Davis double-click occurs.

These two abilities are the ability to withstand short-term temptations and maintain fortitude, and the ability to be extremely confident in one's position and not waver.
