I'd agree with this general sentiment. If I need to finish something quickly, provided it's not ridiculous, I will. Also, keep in mind that when you've been writing code professionally, you have access to either code others have written at your organization, code you've written, or both. At times, this can help dramatically. There are countless times when I think "I know I've done this before" and I rip out 10-15 lines of something I worked on 5 months ago and go ahead and adapt it. There really isn't any reason not to do this, IMO...

Also, in general, I don't get a requirement/feature/enhancement/etc and start slamming away in my editor. My personal preference is to think about it, scratch some ideas down on paper/white board and just stare at my monitor while I run everything through my head. It's always my first reaction to think I need to start typing out some code - and [for me] that's usually not the most efficient approach. Once I have a concept/logical-flow in my head that I have run through several times, I'll write that in my editor as comments. After that, it's really just me writing code that adheres to my comments rather than trying to design the program while coding it.

I'm not at all saying this is the right approach for all, but that's certainly the case for me.
