You should make a list of "things to do" i know yours will be quite large
but it definately helps
I have done it and it motivates me as you tick things off, you do things in a more methodical order aswell
My car is not a million miles off being finished but once you make a list you realise just how many little things there are to do
It helps me get more done too as you dont have those moments where you are stood doing sod all for half an hour to deciding what to do next!
