Bad Taurus traits... how to avoid them?

So .... I really want to become a more 'upbeat' and confident person!! Not dense and slow.... stubborn like I am (I'm a taurus/earth element, which explains everything) is there any possible advice? Even if it takes a lot of practice! I'm up for it, I just don't want to be like such a 'down, calm, weak, dense, slow' type of person, I wanna be like fire! I still want to be grounded and dedicated, focused and all... but I don't want to be dense, it's a bad trait that's a defect especially for career-related! If anyone has any advice, it would be beyond extremely helpful!!
