Routine leads to boredom. When you are bored your brain stops counting what you are doing as something interesting and dosa'e remember it. If you were to think about what you did last week, does anything stand out, or is there nothing special that jumps out at you?
If you have no special memories then you are probably repeating the same things day after day. Get up, go to work, get tired, go home, eat, watch tv then sleep. That's why your life doesn't feel special. You are doing nothing out of the ordinary.
