Dear Mr Moneypit....
I think you are even better organised than me or your list is just much longer....
Me & organised aren't two words that usually go together, but thanks anyway.
I find the best way to approach a project is to break it down into small, managable segments. Ignore all the small jobs to begin with and just concentrate on getting the larger stuff sorted. If a large job is getting on top of you, then break that large job down into smaller segments.
Then once the major work is out of the way, take a step back and take a look at the details.
Make a plan and a timescale and stick to it, no matter what. Ok, so the timescale might be a little flexable, but the plan must stay the same.
To be honest, I have woken up in the middle of the night to add things to the list of jobs that need doing on the Disco. If I dont have my list then I'll go mad. At times it's the only thing that stops me putting a match to the whole bloody thing.
It's all too easy to become dissalusioned with a project. Hell, just look in any classifieds section of a classic car magazine to see all the project cars for sale that are "95% complete".
Like I said, making those dam lists is sometimes the only thing that keeps me motorvated to complete it. Otherwise at times you simply cant see any light at the end of the tunnel.
With the Disco not far off finished, (I reckon another £2000 tops, and done by the end of the year), the next job is a LS2 / LS6 & TKO600 in the Chim, along with new suspension and brakes. Now that is a job that will give me plenty of sleepless nights.
