Do you keep doing the same thing over and over even though there is plenty of evidence that you won't succeed?

yes, like when ive applied for jobs in calling centers only to lose them

I believe that statement is a rough definition of insanity....soooo yeah I occasionally do that! ;)

So what maybe I can stick back the grape this time;))

Yes, it's all I know how to do.

I know, bro. We all keep breathing, and breathing, and breathing, and breathing, inhale, exhale, repeating, repeat. But why do we keep doing this if we know we will never succeed at breathing forever. Who wants to live forever? Connor Macleod from the clan Macleod? There can be only one. 

cus I is programmed to Succeed!! :)

Truly depends on the 'something' we're talking about... Failure is a necessary component of success, as counter-intuitive as it sounds.

Boredom?

Ask me about my efforts to learn how to play the flute at band camp. 
I was pretty good, but could never play a note
