This is an excellent article, I fully agree. I also think that the key to success is mastering one language instead of trying to know them all.
Yes some languages are similar to others and if you can write code with one, probably you will also be able to write some code with another. But it's not just about knowing the syntax, it's also very important to understand the compiler and everything related to that language to be able to write excellent code. You won't be succesful by using "best language" it's more important to understand the language you use well.
Team work is another thing that I also find very important. Working as a freelancer can be nice, but working with a great team is a lot better. It's not just about working on the same project, it's also about exchanging knowledge and trying to be as good as the other members of a team that makes team work great. I have always had the impression that my skills improved a lot more when working with others in a team.
