How do you approach a build?

Thanks see I could have got this running first but thought that once running I wouldnt fix what needed to be fixed. I grew up around cars and with my old man it was like once it was running he was fine with it. But I want something that looks and runs good. Which is why I didnt get the drive train done first. He had so many unfinished projects when I was a kid. I know there are many reasons for that. But I told myself when I got this car I wouldnt do that. It needs floors lower rear quarters but the rest is in decent shape.
