Opposite of Casual

As easy as counting one, two, three I tend to learn with a breeze A fast learner who’s quite free From the struggle of trying to see Plastered with a big smile daily Very determined, not at all hasty Some call me sane but I’m crazy For all things that truly make me Love for art like it’s an addiction Math and science are my obsession Eating food overcomes the depression But being active seems to be the correction Very passionate and loving Kind-hearted and stunning Constantly thinking about future things Just trying to be more than nothing
