Space and what in between .

Let me get this straight.What do you do when you've got nothing to do? Wait.
I know the answer but it's not what i'm looking for ?
Now, What do you do when you're actually doing something you always do ?
You just focus on it and that's all thinking that you have to rest after finishing it.
But Do you think or question yourself that you're losing time ? you're losing time , energy on the wrong things.
Try something else ,Try not to do anything and think.Do we exist? Are we here or we're just in a hologram?
