1. One of the biggest time wasters is procrastination. Some people constantly delay their tasks and find reasons to justify themselves for not doing this task today or tomorrow, and as a result don't achieve their goals. So, never put off till tomorrow what you can do today.
2. Impossibility of making decisions. This time waster steals your time and can produce unimportant or unnecessary tasks. Only you know what you need to do tomorrow or today, and only you can make decision about completing this or that task, as nobody else will make this decision for you. So, make decisions to move forward to your goals and achieve success.
3. Unexpected situations. These situations happen very often. Imagine that when you are going to do your work, some unexpected situation happens and pulls you away from that task or work. You need to think ahead and determine what things maybe go wrong. Plan in advance, so if some unexpected things happen, you can delegate them or quickly solve them and move forward.

Following these methods, you will learn how to use your time productively and avoid time wasters. However, you need a tool where you can keep your tasks and goals. Take a look at VIP Organizer.
