Via Management Tips From Harvard Business Review:

Self-discipline is hard. Try these three tips to make your work more efficient every day:

1. Get three things done before noon. Statistics show that the team ahead at halftime is more likely to win the game. Enjoy your lunch knowing that you accomplished at least three tasks in the morning.

2. Sequence for speed. Break projects into parts. Take on the longer pieces at the beginning and make sure each subsequent part is shorter. If you leave the longest parts for last, you are more likely to run out of steam before the end of the day.

3. Tackle similar tasks at the same time. The mind thrives on repetition. You can build momentum by taking on similar projects at the same time.

Consider how you responded, what went well, what didn’t, and what might be more effective in the future.Never cancel this meeting—it’s crucial.
