Don't be over-creative

This is the most important programmers (I mean beginners 😃) problem I have ever seen. I can tell a story. There is a man who wants to be a programmer. He started from PYTHON, then he thought it will be an advantage if he study JAVASCRIPT also, then he started studying JAVASCRIPT. He saw a video that explains the power of the GO language and he also began to watch tutorials about it and what finally happens, he learnt nothing! (Actually, he learnt something from many languages but it won't be useful). He can indeed do a project in many languages, but the project name is "HELLO WORLD".
