 ### Studying
 
-- There is no silver bullet to help you learn C++ in one day/week/month. Get ready for the lengthy unsupervised learning of all kind of material before you are able to pass the interview to get your first job offer.

 - If you feel that you don't understand some topic, look for alternative sources.
 - Practice and only practice will let you harness C++! You'll forget most of what you read or hear without regular coding.
-- Don't try to write perfect code. Your main goal is to write a big amount of code that WORKS, i.e. does exactly what is required. You need to learn to communicate with the computer. It's similar to studying foreign languages. First you talk sloppily, but then you refine your skills, you get a better feel of the grammar, you expand your vocabulary, and so on.
-- Don't jump at a huge problem at once - like creating your own game. In the beginning you are likely to lack the knowledge and experience to cope with the task alone. This approach frustrates quickly and leads to the disappointment in oneself and one's abilities, forcing to abandon the education. Better progress from simple to complicated, gradually inventing more and more difficult problems for yourself.
-- Don't focus on Leetcode and Codewars or similar resources at first. The purpose of these portals is to refine the skill of the usage of classic algorithms and data structures. These playgrounds are designed to abstract away the details of the programming languages. At the start this won't benefit you considerably, it's better to focus on the language itself and its capabilities.

 ### English language
 
-- It's easier to looks for the solutions in English, but don't torture yourself if your current language proficiency isn't that high. You might get demotivated too soon. Most of the problems you are likely to encounter at first are searchable in your native language.
-- If you  feel that your English is insufficient, start studying it with more pleasant means: series, video games, fiction, news outlets or articles interesting to you. Several months are enough to refine your skills of comprehension in English.
