I'm just not sure if the trade-off is worth it for me to aggressively pursue it or if i should put it on hold for another year so i can learn more practical skill that has an immediate impact to those around me
That being said, focus on just one new language. Three at once is extremely hard to balance without committing a very serious amount of time and having a high level of natural language learning talent. The easiest languages to learn with English as your native language take around 500 hours to reach conversational proficiency [1] which is an hour or two a day, try to learn 3 languages at once and that's nearly a full time job. If you dedicate yourself to spending an hour every day it's realistic to reach conversational fluency in a year and a half or so, if you go more casually it might take 3-5 years or longer.

Is this ridiculously unrealistic or are you actually disciplind enough to pull this off?
Why do you even want to learn 3? There's not that much point learning 3 at once, try learning one.
My favorite quote from his article:
> Musicians get better by practice and tackling harder and harder pieces, not by switching instruments or genres, nor by learning more and varied easy pieces. Ditto almost every other specialty inhabited by experts or masters.
I have reached b2-c1 level myself in only 2 languages, plus b2 in a few more, and a2-b1 in a few more. Some languages I just want to be able to have basic interactions with to speak with a neighbor or a person I always see at a restaurant. Others, I have a personal connection to and want to get to a really high level. It all depends on what your goals are.
If you intend to study 3 languages at once, make sure you're very organized. You should track everything and have a plan for exactly what you intend to do in each language before your day starts. Also, realize that each language will move no more than 1/3 the speed that focusing on a single language would.
Final comment: if you've never learned another language before, I highly recommend to just take 3-6 months and dive into whichever one interests you the most.
There are so many subtleties and history in a language, it's worth diving into one culture at a time.
