Creatitvity is not meant to learn if it is learnt it is not creative but a copy.It is a natural instinct and can only be an inspiration of other's creativity.
The thing about creativity is that it's a self expressing generally speaking it is subjective and personal ( thoughts and emotions ) outlet ... And everybody has something to say , because let's face it , every body has lots of thoughts and lots of emotions .
Now all you need to know is the way of which this creativity will get out to the world , what tool will you need ? Will you need a music instrament , will it be through writing words and imagination, or maybe it's public speaking or maybe through some form of an artistic work that needs clay or rocks . Whatever way you find closer to yourself expression , sharp your tools to make your work advance and better in expressing you .
So in those terms , yes you can learn to be BETTER in your creativity .
