CAN I BECOME AN ACTRESS?

Well so i have my own complexities.i look at my close up and i love it,but then i see my long shot and i dont like it ,its like whenever i see myself act or on camera i always critique myself and cant sit thru the whole performance seeing myself i get very nervous.U can sometimes pass me off as an average looker but then someday's i see the spark in me.well i noe i have it but then i have my doubts of how will i be able to compete with really pretty ladies.its just confusing sometimes.......what do u say?
