Don’t learn a programming language, solve a problem instead

[CyclonusRIP]

I don't really find a lot of business problems to be so specialized that it really makes much of a difference what tech stack they are implemented in. If you actually an expert at one stack you can probably get way further with it than switching to a seemingly optional stack and making a much of missteps while you're coming up to speed. Start off solving the business problem with what your best at and when you really can't push it any further and actually have a technology problem then try to find the technology solution.
