How to be more 'upbeat' & confident instead of dense and slow? Please help?

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!
