Getting Things Done is one of the most popular task management systems. GTD was invented by David Allen to help manage daily commitments effectively. Here's a quick look at how the GTD workflow looks in practice:

1. All tasks go to Inbox
2. Is task in Inbox actionable?
   1. Yes
      1. Who can handle task
         • Somebody else - delegation
         • Me - reserve time in calendar
      2. Takes less than 2 minutes
         • Do it now
      3. Complex
         • Break into smaller tasks
   2. No
      1. Eliminate
      2. Add to list Someday/Maybe

Task management systems will not make you more productive automatically. However, they can give you a very important thing - a sense of control.Although Trask is not stricte GTD tool - but without problems, you can use it like any GTD tool. All tasks that do not have a date assigned go to Inbox. Next:

1. If a task is not relevant, meaningless or not actual - remove it
2. If a task will take several minutes - do it now - do not waste time on planning.
3. If you can delegate task - do it.
4. If a task is complex - split it into smaller tasks.
5. Finally, plan when you are going to execute task by placing it in a calendar.
