You don't make yourself interesting, you get interesting through hardships you go through while living. Similar to how scared people looking interesting because you wonder what is behind that scar it is with personality. The more someone went through while maintaining some mental stability the more they can tell, generally. This however does not mean that you should go and try to force something, that would be foolish. As other people have said, playing videogames and browsing the internet does not provide a fragment of the chances that you will gain life-experiences than leading a healthy life. This is no reason to sulk though because that means (even though you are on 4chan) you probably have a rather stable and/or secure life. Wishing you all the best.
