It will be done when it's done, try not to say I'd like it done in x time or by x date, that can be very discouraging.
Focus on one thing, finish it. As it is nearing completion start planning the next step.
On my two project one took two years, the other six and a half. Although my Barracuda only took two years it sat largely untouched for 18 years, with my Polara I was thinking it would be a two year project, it ended up being six and a half.
Been there, three factors impact your timeline. Time, Money, Space. Try and set aside time, Saturday mornings are for the car, wife is at yoga on Thursday, that is my car time, you can always spend more but have a plan. Budget, small or large try and have an idea what your budget is and set it aside, I told my body guy I had $150 a week, he could work as much or as little as he wanted but I would only pay $150 a week, we kept a log, got it done. Nothing is more frustrating than constantly moving things to work, everything from having to clear the car off to clearing the bench, I bet I spent 10% of my time just dealing with the lack of space.
As already said, baby steps. Break it down into small projects and finish them.
For me having another classic to drive helped, I didn't feel like I was missing out. When I did my Barracuda I had a Valiant as a daily driver, with my Polara I had my Barracuda.
