If you have decided to lose some dozen kilograms it seems that nothing can stop you from this, but it is not so. Even the most determined people gradually lose motivation if they do not have any plan for their actions.

So, the first tip is: make a plan. It may seem weird, but it is a well-known fact that people who are a success in something always act according to some plan, be it official or semi-formal. It is really much easier to reach a certain aim when you know what to do as well as when and how to do it. So, you should sit and describe what you want, by what time and how you are going to gat it. Your plan should have one long-reaching aim and a few sub-aims that will help you to reach the final goal.
