On a micro scale, I use pomodoros for this (http://en.wikipedia.org/wiki/Pomodoro_Technique), but on a bigger scale, I often find that I'm subconsciously weighed down by worrying about things that I'm not currently doing anything on. Have to remind myself to just get moving and figure things out as I go.
My long streaks of working out almost always start with a couple days at the gym basically screwing around. I know it's not optimal, but it's something, and I gradually get more intentional and serious as I keep going.
