"A young friend trying to make his way"

I think he is still in the process of getting to know himself and finding his way. Now when I look at his profile and chat with him, I see that he is interested in many things at the same time, which is actually a very good thing, and I know that he will choose a field for himself and go to a really master level. He produces good content using his computer knowledge and crypto knowledge. If he takes himself to an advanced level, I know that the projects he produces his content can develop himself. So I would like to give the following advice. Don't know less in 100 things, be the best in one thing, my dear friend.
