Write Everything Down
You should write everything down. I need to do this today. Tomorrow. When I’m at the pharmacy. When I’m at the computer. If you don’t write it down, it will either occupy your mind at times you should be focusing on other things, or you will forget it altogether.
Organizing what you write down is the biggest challenge and will reap the largest rewards for you. I could go on and on about how much easier this has made my life. But instead, I will just point you to David Allen’s book – Getting Things Done. Read it, implement its principles, and you will no longer worry about what you should be doing. It will be automatic and you can then focus on execution. He calls it “Stress-free productivity.” I agree.
