I am happy right now and it's mentioned in the happy thread, but I am also thinking that I need to drink more because my life is so meaningless. It's not a happy thought.
Go make some friends or translate some poetry~
Alternatively, learn AI programming and go make some friends! /awful programming joke
More seriously though, not everyone needs to be super-inspired by some long-term fantasy about how they want their lives to turn out. In fact, it's probably better that most people aren't. Dreams and inspirations fade quickly with ever-shifting opportunities and events. Simply accept that most of everyone's lives will be uninspired and seemingly meaningless. Personally, I've gone through most of my life completely uninspired, without any particular heroes or such.
So what do we do for those parts of our lives? Well, personally, I try to use them to acquire as much knowledge and as many skills as I can which might help me for those occasional bursts of inspiration that we see as giving meaning to our lives. Just wasting time playing minecraft, kerbal space program, or similar? Sure! Just put up some Coursera lectures on the side while playing, and you'll come out of each day with more knowledge than you would get from a university. Even doing the most mundane, "time wasting" activities can thus be made to help give your life meaning by preparing you for the occasions when the possibility for meaning does show itself.
