I'm so fucking done with this project already

I'm removing rust above the windshield and on both sides where the roof panel and side panels meet. I was hoping to finish in one day, but I spent all of yesterday on it, and I've been working since 7 AM today with still more to do tomorrow.

• Taking off the roof rack was a pain, and putting it back is going to be just as bad.
• The seam sealer on both sides was an absolute nightmare to grind off.
• I went through four rounds of grinding, applying rust converter, wiping it off, and repeating the process—yet there are still small spots of rust left, and I just can't be bothered anymore.
• It's near freezing, so I'm running a 3kW electric heater, which is going to cost a fortune.
• I didn’t do enough sanding, so now the line between the old and new paint is going to be visible.
• The antenna would've been a huge pain to remove, so I didn't and that’s probably where new rust will show up in a year or two.
• I also did a poor job masking before applying the zinc primer, so now I've made a mess I have to clean up.

I just hate it when you try to do a good job, but everything seems to go wrong. You get frustrated, start rushing, and make more mistakes, and in the end, you’re left with a sub-par finish that you'll probably have to redo in a few years because you didn’t do it properly the first time.
