功勞的實值可在每人上判出。
它不在於明顯度，也不在於佩服人數。
它在於累積的，還是臨時的: accumulative achievements are like piano skills and those that no one can freshly imitate, these are true value; show-off achievements are like introducing a friend to another friend, etc., these are easily imitated by anyone.
Anyone claims to value the show-off achievements and have not accumulative achievements is finding excuse to be stupid. And if he/she claims ownership of the show-off achievements while preventing others for the same achievements, he/she loves to look down on others.
