Such hubris can be fatal

Hi

Would you say that the use of hubris is natural here?

Success went to my head. I became a name-dropper. It was only my wife and daugher who brought me down a peg or two. But there were many more to inflate my ego. I began to think of The Illustrated Weekly as my child, that it would languish the day I left it. Such hubris can be fatal. My day of reckoning was not far off.

Thanks,

Tom
