I'll toss my bit of advice into the void too. One thing that helps me at least is to have different locations for different activities. To have "this desk is my work desk, while I am at it, I work." I don't think this is the only thing you should do, and obviously not everyone has room in their home/apartment/whatever for a desk & room dedicated just to work... But it can help. Coworking spaces also help a lot with this. If you don't have room for a second desk, you can get some of the effects by simulating it. Before starting work, specifically get up, walk around the block (your commute), and then when you get to the desk, make a specific change to put it in "work mode". This might be something like using a different keyboard for work vs not, or switching to a different computer login for the duration of work.
