Effective working at audio/video editing sessions (avoid fatigue making steady progress) Background

I've just completed an editing project to produce video highlights of an awards evening for my local community radio station. It was a voluntary non-paid project and I'm very pleased the results I achieved - and more importantly, the station are very pleased with it too. But, as with many other previous projects, have found editing can be tiring at times. I have a full time job in computing but unrelated to video editing (funds all the software and equipment that I learnt this stuff on!) and usual housekeeping commitments so I had to produce this work from a number of sessions, some into the early hours. When I know I have to resume the work to get it done I procrastinate and do other jobs sometimes before I finally get in the zone, once in the zone I get frustrated when I have to stop to meet other commitments: sleep, work etc.

Any top tips to bear in mind for a future project?
OK, I'll have a go. Here's my own answer (and advise I should take for myself - which I actually did do to some extent):


Avoid procrastination. Start small. Start with doing something. Don't hold up too high expectations to put yourself off. Good ideas here: http://zenhabits.net/dead-simple-guide-to-beating-procrastination/ (I succeed a bit with this advice, BTW I have no affiliation to zenhabits)
Regularly deliver draft work in a complete state to the customer. This rewards you. It gives them confidence that this is being done. It gives them opportunity to give feedback during the process (to avoid unnecessay work or deviation or disappointment). It gives them something to do on in the event you are delayed later, due to illness or other commitments.
Take breaks.
Track progress to help predict how long the remainder may take.


I'd welcome anyone else's input. I'm really answering here because no-one else has yet. I'd welcome some enlightenment from your own experiences.
