How can you save time?

How can you save: up to a full hour a day. How does it work: write down a list of what you have to do that day. Select the five most important things from of it. Rank them in importance from 1 to 5. Begin with the most important. Don't get distracted or interrupted until it's done. Only then start on the second. Finish them all like this. Restart and arrange the rest of your day and your life according to importance. Win one hour per day, that is 365 hours, 1.5 months of eight hour working days, per year, this is an extra 10 years on an average human life. Live long and prosper.
