A Joosr Guide to Getting Things Done by David Allen

Treat your work life and your personal life with the same consideration, tackling your inventory of pending issues with a consistent system to get things done.
Think of your goals as belonging to one of six dimensions, starting from the ground level for the more trivial and accessible, and working your way up to your ultimate purpose or vision.
Apply a five-step planning system to all your endeavors, great or small: record, all pending issues; assess their importance and whether they should be acted upon; decide on the optimum path; envision the results and reflect on the outcome; tackle each task as planned.
Review your progress regularly, reassessing your perspective and how close you are to achieving your goal.

As you strive to complete these goals and work your way through these dimensions or horizons, you need to be fully involved in the task at hand, but still maintain a sense of awareness of the wider aspects of your projects in order to work at full capacity.

Whichever way you choose to go about getting things done, the horizon metaphor will serve you well. There are two organized ways to do it, namely from top to bottom, or the other way around.

While the ultimate dimension is always the top horizon, every mundane and tedious task we accomplish gives us a sense of empowerment and freedom, and eventually gives us the resources to work our way up to the greatest goal on the agenda.

Your review and reflection on the tasks at hand should be an ongoing process, and you need to use every opportunity you have to set reminders, alarms, and notifications for outstanding tasks.

When you have a weekly review set in place, you can catch hold of all your loose ends, and marry the important commitments with the mundane tasks

Tasks you’ve classified as doable should go on a list of projects, be it paper-based or electronic, and should be accompanied by supporting material and reference files, all of which must be reviewed regularly

If what you’re reading on a post-it can be done now, do it.

Once a pending issue has been acknowledged as something that requires your attention, and recorded for future reference, it’s time to decide on the best course of action.

Keep a record of everything that requires your attention. Transcribe and store that information in your “inventory” of pending tasks.
Assess the importance of each record, identify those that constitute doable tasks, and decide whether to act upon them.
Visualize how you would coordinate your next steps, and decide which path to take.
Envision the results and reflect on the outcome.
Take action: tackle each task one by one.
