Sobre mi

Em dic Kuba, sóc polonès, però visc a Hongria. Tinc 22 anys i ja parlo quatre llengues: polonès, anglès, castellà i hongarès, però entenc més de quatre llengues, per exemple alemany, txec, eslovac i també portuguès. M´agradaria aprendre el català, perquè tinc molts amics a Barcelona, València i a altres llocs a Catalunya. Acudeix Sovint passa que els meus amics parlem amb mi en català i jo responc en castellà. Tambè m´agrada molt la música catalana, de Barcelona Manel, de València Atupa (però són só això només són alguns). En el futur voldria traduir del català al polonès per exemple. També vull viure a Barcelona. Aquest lloc és molt important per mi - allà em sento millor.

Todo correcto. El único comentario es que yo diría "toma café", sin artículo, particularmente en negativo (¨nunca tomo café")

I think that, once you get used to read without nikud, the hardest part is the use of prepositions and the verbal system.

The Utility as a term in the Economic theory

The term Utility has an important role in the economic theory, and every first year student studying introduction to microeconomics deals with it.
The main idea is as follows the following: the economic world is divided into two main sectors: the firms, which produces goods, and services, and the consumers, which consumes them. Of course, the consumers on the second side are the are at the same time workers of the firms on the first side, and thus they produce the goods and the services they consume, and pay for them (as consumers) with the money they earned (as workers).

The goal of the firms is to maximize their profit: as much revenue as possible combined with as few expanses expenses as possible, [suggestion: maximizing the revenue and reducing expenses results in...] results in the highest possible profit. One may argue and say that profit and money are just a mean means to an end (and that is true); however the role of the firms is to create profit.

What is the goal of the consumers? Why do they consume goods and services? The "thing" they get from it their consume is described as called "Utility", and the consumers objective is to get as much utility as possible. Given that a consumer has a limited amount of money, he will consume it in a way that will enable him to get as much "utility" as possible. The notion of the utility generates, yields discussions and conclusions like the following:
* The reason why water (vital material) is cheaper than diamond (nice to have).
* The reason why we gamble, though  in even if on average we win less than what we pay. lose. 
- The existence of the demand curve, and the reason why we buy (and even spend) more when the price is reduced.
* The way we divide our time between working (in order to get as much money as possible) and consuming (in order the get as much utility as possible).
* Last but not least: why do we work? (spoiler: not in order to earn money but in order to spend money..).

All those   these discussions applyies of course to the rational economical behavior of the consumers, though many aspects of the human behavior is  are not (and not supposed to be) rational or economical (and are not supposed to be either).
