''You are what you eat” ''You are what you eat” (G. McKeith) The food that we eat have a tremendous impact on our health and most illnesses have their source in our diet. Unfortunately many people do not see this association between food they eat and their health. They take care about the oil’s quality they put in their cars but they don’t about the quality of food they put in their mouths. The easiest way of being aware of this is to read food’s labels. It is time consuming but it is worth doing it. The beginning of this activity can be tough a little bit when you have never done it before. But after reading some articles and asking people that they work in this department you can obtain the necessary knowledge that will be crucial to be used in the “food’s world”. I did so! People can always make choices what to eat: a chocolate bar or an apple. And eating each product leads to some consequences in their bodies and behaviours. Chocolate contains simple carbohydrates that stimulate the insulin hormone to work and reduce the level of them in the blood. Because of that people are hungry again. On the other hand fruit and vegetables (there are only few exceptions) contain different type of sugar which does not have the impact as chocolate does. And in addition to that it contains fiber as well. Fiber is an ingredient that has no calories but make people full. To summarize eating an apple instead of chocolate bar is a power of will that really matters.

Coaches are the best teachers Everyone has goals in their lives. But some of them are able to achieve it without anyone’s support but the others not. It happens very often that we do not have enough motivation to enforce the goals in our lives, because we are afraid of being rejected by the family, friends and society. Everyone has a need to be loved and accepted by the people that we care about. I think that coaches are the best teachers. They help us to achieve our goals without any suggestion what we should do. Thanks to them we realize what is important for us and what we really want to do. And the idea how to achieve our goals is just coming into our mind. The meetings with coach are held systematically, which encourages people to be motivated.

The decisions we make Everyone makes decisions in their lifes eg. what to eat today, which kind of transport to choose, which requirements to fulfil etc. All our lifes are based on making decisions, less or more important. Sometimes only one decision can have a tremendous impact on our lifes, it can change it completely. Some people like being advised what they should do and the others make decisions by themselves. The first group of people regrets that they did so when they realize that their decision was wrong. They also complain about all the exterior factors that they do not have any influence for (economical situation in the world, bad weather etc.) and these factors cause their misfortune, they think. They do not see that the cause of their misfortune is inside them. The easiest way is to get rid of their own responsibilities and transfer it for other people. But the fact is that only we are responsible for our lifes even if other people advise us what to do. Only we, not they, should make decisions in our lifes and bear the responsibility of them.
