I think optimal level of perfectionism depends on impact of the decision and how hard it will be to change in the future. I think it's worth to be perfectionist when it comes to architecture, which is hard to change. So you want to make sure you do things right (or extensibly), and consistently. However, in minor things like method names or code structure, it's OK not to be consistent. I would also say being able to identify where you should be consistent can be itself a huge productivity enabler.
