We are living in such dynamic period of time when many work tasks are mixing with out personal life. We are getting every day emails, call phones, issues , tasks to complete.
Sometimes probably we are feeling our head is ready to blow up from a lot of things we should remember to do.
So we just need to find any more effective system and don’t trust on our memory.
Book “Getting things done” written by David Allen could help you to understand where are the problems and to find different ways to solve them.
There are some steps for beginning:
1. Get out of mind all incoming tasks
2. Collect all incoming data in any comfortable way
3. Process it
4. Organize it
