I've also read that Theodore Roosevelt lived with 'uni-polar hypomania'. There is certainly a link between success and this trait. But.. as mentioned above.. in the absence of depression it doesn't seem like it would be 'bipolar disorder'. However... what if this constant state of hypomania leads to considerable problems in life? If everything is a wreck around you despite your current obsession, job, etc... and you can't control it .. then???
