Answer:
"Mental clutter" refers to things you are worried about that keep you from getting started with your schoolwork.
Step-by-step explanation:
The definition of mental clutter is as the actual physical clutter in a space but applied to our thoughts and actions, when we have a cluttered space it is hard to move and to do things since everything is disorganized, so mental clutter does not let us advance in our mind because we have so many distractors that take us away from our objectives.
