What do you do in RS?

My favorite thing to do in runescape is combat. I would usually just do a slayer task or just run from one combat based mini game to another. I don't like sitting on one thing for too long or I'll get bored, thats why I enjoy combat, cause there are many different things to fight. However i have decided it's about time that I got a 99 stat. I have impressed myself with the fact that I have chosen to get 99 fish and have actually stuck with it for more than a week anywho, that's me rs life for ya
