How can a 14 year old pianist/keyboardist (plays various genre except clical) get discovered?

Talent shows , party's ,if you write send your material to different publishers, when you get older go to every open mike you can perform at . you might even win the nightly prize,keep performing try to learn everything you can along the road . it does not happen overnight.look at bonnie raitt - 30 years of playing coffee houses- then all of a sudden 5 Grammies in 1 year .play for the love of music the rest will come if it is meant too. good luck.i have been playing 42 years - i play very well , but the big break was not there for me or maybe i just did not want it bad enough.
