Or you could (gasp) actually learn/use more than one language at once. Sane people don't switch from one language to another -- they use the best tool for the job, when it's needed. I probably use between four and eight different languages a week, all of which I'm proficient in. I use them for different jobs, because they (or their libs) are more or less suited toward the task at hand.

And moreover, why the fuck should anyone have to "sell" you on a language? You're not buying the damned thing; it's free. Use it, or don't. Actually, don't. We need fewer entitled-feeling developers like you, and more people who care about improving the community.
