I did most of the work, but I did contract some of the graphics I had trouble with to a designer, and I've taken someone awesome on board to work with music companies and other "strategic" stuff for the future.
(not) Properly tracking my time is my biggest weakness.
Personally I track time using Excel. I have a table of start time, end time and a category and desc.
I set up a macro to create a new row, another to create a new task after the previous. It takes me about 5 seconds to "start working" and about 30 seconds to "end" and type in a desc.
It's great later when you need to have precise timing to see if you hit your estimates. I got into the habit when I was developing custom firmware on contract at Technman.
I see it as a huge motivator. I don't track time when I am not working - so it highlights for me the holes in my productivity when I slip.
I also wrote some Ruby scripts for parsing exports from it and making cool graphs
My mind usually races a million miles an hour when starting new projects and I end up doing a little bit of everything.
