Better to work only for Google?

I present my problem.

The situation:

- To write 1 new content I need N minutes
- To share this content on social networks I need 2 times N minutes (total 3N for each content)
- The organic visits that come from Google represent 75% of the total
- The visits that come from social networks represent 6% of the total (I share on a dozen social networks my contents, evidently bad)
- None of my students come from social networks

The question is:

- If instead of using this 2N time to share a single content, would I use it to produce 2 more contents?
- Would I get a lot of additional traffic or lose some of what I already have (given that Google would see the number of social interactions drop to zero)?

Thanks in advance to everyone who will answer me

The only noteable social media which is still sending decent traffic is Pinterest. Social media sites do not like if you send their users away from their platform cuz they earn more money if the user stays on the platform, this is why most social media is about images, videos and worry little actual content.
Don't bother with social media, instead write another post

Traffic from google take time.You need to rank first.
and why not do both, spent 75% time on content 25% time on Sm. if you got budget you can find cheap VM from third country to do the SM,
