No one can put it better than the guru of productivity- Brian Tracy. This is from one of his newsletters – which is exactly how one should improve their productivity.

Zero value add from my side

• Develop clear goals and write them down.
  Because higher productivity begins with clear goals, goal setting is a key component of our coaching program. As you know, a goal must be specific and measurable to be effective in guiding your behavior. It must reflect your beliefs and be within your power to achieve.
• Write a clear action plan.
  Next, if you want to turbo-charge your productivity, make sure you have a clear, written plan of action. Every minute you spend in careful planning will save you as many as ten minutes in execution.
• Set your priorities.
  The third step is to prioritize your list. Analyze your list before you take action. Identify and start with the high-value tasks on your list.
• Concentrate and eliminate distractions.
  In this step, choose a high-value activity or task, start on it immediately, and stay with it until it is done. Focusing single-minded attention on one task allows you to complete it far more quickly than starting and stopping.
• Lengthen your workday but increase your time off.
  By starting your workday a little earlier, working through lunchtime, and staying a little later, you can become one of the most productive people in your field.
• Work harder at what you do.
  When you are at work, concentrate on work all the time you are there. Don’t squander your time or fall into the habit of treating the workplace as a community where socializing is acceptable.
• Pick up the pace. At work, develop a sense of urgency and maintain a quicker tempo in all your activities. Get on with the job. Dedicate yourself to moving quickly from task to task.
• Work smarter.
  Focus on the value of the tasks you complete. While the number of hours you put in is important, what matters most is the quality and quantity of results you achieve.
• Align your work with your skills.
  Skill and experience count. You achieve more in less time when you work on tasks at which you are especially skilled or experienced.
• Bunch your tasks.
  Group similar activities and do them all at the same time. Making all your calls, completing all your estimates, or preparing all your presentation slides at the same time allows you to develop speed and skill at each activity.
• Cut out steps.
  Pull several parts of the job together into a single task and eliminate several steps. Where you can, cut lower-value activities completely.
