Best of worst VS Worst of best

i like to think i am smarter than others, mostly. i am not only can think, generate new ideas, but also make them real.

But the truth is, i am smart just because others are not so good.

take chess as an example.

i beat many people, does it mean i am smarter?

may be, but the more reasonable reason is, i play more.

when practice chess with computer, i knew there are many many tricks and skill i dun know. and my national ranking (if there is any) is below mean of the world chess players.

Thus, the reason that i always win is just because my opponents are not chess player or not played more than i do.

I suddenly recognized that it is so danger for i did not notices that before.
