make video games or animated movie shorts with revolutionary socialist narratives (yes you can make the next Disco Elysium)
learn mandarin move to China and use your skillsets there (to begin with become a "digital nomad", for example, in China)
discover and learn how to organise a vanguard to build pro-social sectors; this will involve the organised accumulation of capital which you cannot do alone
learn theory as you attempt to solve problems; for example you may want to develop an art to educate others on socialism and you may use the narratives of historical figures such as Stalin, Mao, Ho Chi Minh to do so - this will involve educating yourself of their history, reading their literature etc
branch out from your skillsets; video game building may lend itself to other app building. You may for example able to build the beginnings of a Wechat equivalent that could be side loaded to android that comrades could use to subvert the capitalist state with its own communication and trading protocols
intelligence and knowledge is developed; they are skillsets like any other
cross the river by feeling the stones :)
if you find theory overwhelming then to begin with go to redsails.org pick an article that takes your fancy, go through it slowly and may be read one or two references that peaks your interest at the bottom of each article. If you haven't read one already here is something to start you off: https://redsails.org/why-marxism/
join a real life socialist group outside of the internet (they will inevitably have their own failings and contradictions, may be as a litmus test they should understand why a dictatorship of the proleteriat is important and not be reactionary, and should have actual plans on how they may help out the local community with tangible benefits); if / when you do this make sure you have a separate phone with a separate email/online identity for this if possible

Addendum - I may have misunderstood when you said "video games" as a skillset (ie developing them as opposed to playing them) and used that as a jump off for the above. I will leave this post here instead of deleting in case someone else finds it useful.
writing; long or short stories (Stephen King's On Writing if you wanted a starting point), maybe set up an account on Medium (for example) and start posting? Maybe link it to your own patreon page when you feel comfortable?
drawing; from short form comics to graphic novels (lots of youtube channels but a jump off point for structured lessons could be drawabox.com)
music (again multiple youtube series and music tab sites, may however cost more buying an instrument and even more if you wanted to set up some sort of production suite - computer/software/audio equipment)
video; wouldn't know where to start here for actually learning the skillset but the outlay for equipment could be potentially expensive though a smartphone with a camera could be sufficient to begin with (if you want inspiration look up a youtube series on video essays called Every Frame a Painting). If you develop drawing as a skillset you may want to veer into animation instead.
video games; not sure where to start - again searching youtube though I found this for inspiration: https://www.freecodecamp.org/news/how-to-make-a-video-game-create-your-own-game-from-scratch-tutorial/
Top of my head, brainstorming/freeflow:

How do I build an art form that sounds fun, but I have no idea how to do that, it seems a lot of art forms have already been discovered
Completely up to you:
