The first draft of a novel is all about finishing. It's like running from a giant boulder that's trying to crush you: you go as fast as possible, and you don't look back. Speed is helpful because speed means you're working on it on a daily basis, and the more mental space the draft is occupying in your head, the better you're able to build connections between the various moving parts and also generate new ideas that feed into the old ones.
The secret to finishing is momentum - a compulsive desire to keep going until the thing is done. The momentum should pull you along with it, forming a consuming desire to finish.
That's why distractions are bad - distractions pull you out of the draft and wasting time on reddit isn't a good way to get writing done.
Sometimes shittier technology represents a better way to do something, because it's the absence of features that's useful. I do my first drafts with an iPad and a Bluetooth natural keyboard (since I have mild carpal tunnel symptoms). It's great because it's hard to multi-task on an iPad - switching to reddit takes effort and palpably interrupts your workflow. If you're not editing a piece, and just focused on production, an iPad is great.
