Turtle rush

I've been wondering, by starring at my turtle constantly swimming at one corner of his tank. He knows he's not getting out that way. But he just keep swimming at that direction. He stops once in awhile to breathe and then continues.

I thought about myself. If I know doing something will never work I won't do it at all. I won't even try. 

So now I wonder does my turtle has such determination and that I should have the same determination too despite him being so cowardly at times. (I mean he's scared of a lot of things but he doesn't give up) or he's just plain simple minded. 

Oh turtle. I wonder what he's thinking.
