This sort of strategy has worked quite well for me over the years. It takes a bit of practice to get right, and probably isn't for everyone.
For me, it's mostly about knowing the things that I have to do, and just doing them whenever I feel like it. So long as I feel like it some time before the due date, it works out great! In the case where I never feel like it, then I force myself to start with sufficient time before the deadline and power through in one sitting. I find that so long as you know what I need to get done, and give myself enough lead time to stay ahead of my deadlines, it's a workable strategy.
For example I knew that I want to look for a new room. I couldn't start it because I did not know how much time it would take. This makes it really hard to start.
When I finally started I just said that I'll do it until 8 pm or something. This makes it easy to not stop cause "oh it's only 30 minutes I have to do this then I can go take a shower".
This is why I think techniques like pomodoro can really help someone. It's just hard to start something, and more you do it, more you know what's left. Usually this stops the fear for me.
