That's like a bridge being halfway built

If you do it right the first time you won't have to do it a second time. There also may not be a second time so you should do it right the first time. It makes no sense to rush just so you can say "I did it." You can only say "you did it" if you did it right and it won't have to be redone. That's like a bridge being built half way to the other side then you stop. No matter how well what you built was made it won't help anyone from either side. When there is something that you must get done and you find yourself rushing just to say it's done remember the bridge isn't done till you can get from one side to the other.
