Ask HN: Bored at my dev job. Don't know what to do

I've been working at this company as a developer for a few months right after graduating. Company is great, it has many perks, and people there are great. But I am just bored doing stuff that I do. At the end of the day I just come home and realize that I did absolutely nothing useful. I just want to feel alive or something when I am trying to solve something interesting and important, like applying some algorithm to solve some problem (like in uni assignments), or just believing in something that could make an impact on the world (like developing my hobby projects, but I haven't had any new ideas in months). I can't really quit, because I have no social skills to find a new job, especially something really good and interesting. I have no ideas on my own (if I had something I believed in, I would quit the next day). I am in UK now. And I believe I am a quite good developer, been developing since 13 years old. What should I do? Days just seem to pass so fast because of this boredom and monotony and it seems I am wasting my time doing nothing... I am 23. I don't care about money, I don't even care that much about working overtime, I have so much energy, I want to help change the world or make an impact on it, or at least have a slight chance doing that.
