Any linguist here?

Are human languages just the same human experience only with diferent words and grammar but basically the same experience just diferent coats of painting?

So far I'm learning a bunch of languages and is fun, but I wonder if there's a deeper diference between them.

So far my native language is spanish, which I find is ok, but nothing remarkable.
However english is more technical, feels more like a language of engineering and science, but is less romantic and less lazy than spanish.
Spanish feel like a lazy language.

So far I've been trying to learn japanese and It's like an alien language, but overall the same core human experience is there, just diferent.
Japanese feels like a more contemplative language where I need to take my time and have respect for others.

Dunno really how to explain it better.
