I really want to become a bollywood actress?

Hi there.i am an 18 year old girl .i love acting and would like to venture into this profession not because of fame n everything but because i noe i can act and i am a neutral in front of the camera.Lately i am beg ninny to feel insecure about my height as i am short and often compare myself to tall bollywood actress who r less on talent but more on looks.i really wann do it but just feel that because i dint have any filmi connection or maybe because i dint look tall lke katrina,i may not be able to make it there.its a tough world i noe but pls tell me should i feel self conscious of my looks and hate myself.i just wanna act love it and wanna be there at the top.
