I cannot imagine the life of a person running out of ideas. Sure, I hit a dead end every once in a while. By choice I stop from thinking further, but really I sometimes think I am overflowing with new things to do, accomplish and create.
I have endless lists. Sometimes creating a list makes me feel good because I am made to believe that I would do this one day. Go through the list and just DO IT. If only I had the time!
So, yes I guess I am a hyperactive thinker. Give me a paper and pen and I can jot a whole note-full of thoughts, doodles, scribbles and ideas. My mum was right after all (aren't they almost always!)
