“A creative artist works on his next composition because he was not satisfied with his previous one” – Shostakovich
I also take this to mean that a creative artist finishes his current composition in order to start a new one.
Finish your work. People often say that they have a lot of unfinished projects. I think that this is often the case because they are afraid that it will not live up to their high standards. Well, finishing the work is often the hardest part. In order to finish a great work, you must learn how to finish a great work.
Furthermore, finishing a work and seeing it in written form is one of the greatest ways to learn. When you see your work in front of you, you can also see the errors, as well as the great things. You are able to think new thoughts that you were not able to do so before it because you no longer have to have it memorized, you no longer have to develop memorized thoughts from memorized thoughts, but can develop new thoughts and ideas from those already written down.
