Sitting here looking at the shit spaghetti I wrote yesterday (that works) and wondering if it'd be easier to add more spaghetti for the feature I need to add or "do the right thing" and fix 1800 lines before I move on...

Did first. Did regret it. Do the right thing, it will help in the long run and most of the time even saves performance!

I habdle spaghetti code like I handle my real spaghetti: cut it up in nice, small pieces that are effortlessly processed hehe

It really depends if you give a fuck or not.

I give a fuck and try to refactor bolognese when i see it, others from the team are just patching up with more bolognese.

I am being their janitor and cleaning up their shit on a regular basis. Do your team mates just patch it up with more spaghetti or do they care? Do you want to be the janitor?

Its up to you!

Update, 24 hours later...

Code is clean, extensible, well commented and beautiful.

I can now start the 45 minutes of billable time for the next feature.
