You need to not only plan your day, your week, your month, but the next 3 months. This will help you determine not only if you're hitting your big goals, but also how effective you are at doing so.

I use 3 tools to help frame my planning.

1. A time management software like TimeDoctor.
2. A digital calendar like Google Calendar or iCal.
3. A quarterly white board (see below)

Place your major milestones for the next quarter on it and put it in a very visible place.

These 3 tools will make sure you never miss any deadlines again and help you visualize what you need to get done.
