I worked with information for many years. Created a site "Search - Fast" about a quick search on the Internet. The PoiskBystro channel on Youtube has over 4 million views. There are free videos with step-by-step instructions on how to quickly and free search for information on the Internet. Time is the most valuable resource and it must be protected. The result is important, not the search process. I teach not to search, but FIND. Do you understand the difference? You can search endlessly without finding a result. My advice leads to a quick result either in the form of an answer to the question, or in the decision not to waste time on further free searches. If the result is negative, it is better to contact specialists and save your valuable time. After all, time is the only thing that cannot be bought for any money. And this is the only non-renewable resource. As the song "Chaif" sings: "Time does not wait."
