Splendid quote! I remember way back then my friends teased me for me being a negative hence the so called negamind. Basically in arts there are times that you think that is your limit and you can't do anything about it. But the art speaks up and tell us to stand up and pull yourself together.

Art can also be a medium for the message to be delivered in the mind's of the viewer. Not all kind of art are made just for entertainment but their are some art that can be an eye opener or message for everyone. Just like this picture at the left, it shows that if you're not struggling it simply means that you are not giving your best shot.
There are also some arts that seems to be talking to viewer or at some point breaking the fourth wall. Art is just so amazing and full of varieties. Maybe one day you'll be reading or viewing an art made by yours truly. Remember Be an Optimist Prime!
