These are all great excuses, good for you.
But just think, the time you spent on writing your excuses you could have very well spent on drawing or studying art.
(Unless you do not wish to be an artist, however if you do, you need the right mind set for it...as long as your putting excuses above actually trying you shouldn't expect to get anywhere in the world of art, it doesn't just happen overnight, it is hard work much like anything worth achieving)
