It can be done. Sometimes.

I am so proud and happy, when I can make a seemingly complicated change quickly, because the architecture was well designed and everthing neatly seperated.

Most of the time though, it is exactly like you described. Or randalls good code comic:

Allmost too painful to be funny, when you know the pain is avoidable in theory.

Still, it should not be an excuse to be lazy and just write bad code by default. Developing the habit of making everything as clean, structured and clear as possible allways pays of. Especially if that code, that was supposed to be a quick and dirty throw away code experiment somehow ended up being used and 2 years later you suddenly need to debug it. (I just experienced that joy)
