For this technique you need a calendar and a red marker. Every day you work on your project put a red X on that day, in your calendar. Try to keep the chain going as long as possible. 8 days, 30 days, 100 days. If you break the chain by not working a particular day, just start again. Imagine Jerry Seinfeld's voice in your head saying "Don't break the chain!"
I used this technique to write Apocryphal Lorca. i worked from August 1 to Christmas without breaking the chain. Obviously I'm not a normal person, but this technique might work for you if you have a hard time with continuity of effort. Even a few months of chains of 5 or 8 days apiece will produce results beyond your wildest imaginings.
If you do break a chain, do it for only 1 or 2 days at a time. That way you can take days or weekends off but without losing continuity.
