I know this feeling, but you know, I decided that it's better to finish what you have started, not out of some stubborn need to prove that you can, but because it's better to continue, but keep your design fluid.

First ideas or thoughts seldom turn out how you want and, to leave you with another platitude, practice makes perfect
