There's a wonderful sequence in a film called 'Fame' by director Alan Parker where a student in an art school dabbles in different art forms. When he goes to dance classes, he is told this is the best form of art. When he goes to drama classes, he is told that theatre is the amalgamation of all arts on one platform. And finally, when he goes to the music class, the music teacher says that music beats all other art forms. So, if I'm doing theatre, then of course for me, theatre is the highest form of art but the same holds true for poetry, music, dance, painting, and cinema. So, whatever your chosen discipline is, it becomes the best form of self-expression.
