sometimes you just make art to get it out of your system, you dont necessarily have a grand idea to convey, youre not trying to improve from your previous work, or trying to find new and novel process in making your work.
im well aware of 'making art for the sake of art' but when you're an aspiring artist who is trying to "make it" and do this for a living you could forget that it is also still possible to do it as a hobby.
