I've personally found a variation of Marc Andreessen's index card concept very useful. (couldn't find it on his blog any longer, so here's an archive.org link)
I typically write down one simple goal each day for whatever project I'm working on. Something that is easy to knock out, but meaningful. Day after day of tearing up index cards of simple goals, and sooner than later you've accomplished a lot while not worrying so much about drowning in the grand scheme of things (I typically get overwhelmed / overloaded by having too many things that need to get done).
