Thanks for sharing your idea and opinion with us, i am not professional but i post in categories of writing and poetry and yes sometimes when we write so much an time comes where we think that we are lacking idea and in those times it's better to hold some time instead of writing ineffective things. In times of adversity of ideas and topics, as you said we could watch movies because movies go through an story with association of different aspects of life so movies can expand our vision, and most important thing is go outside and in my opinion there is no better teacher than nature, and nature can refresh our mind and inturn it will help us in producing new ideas and content because quietness and peacefulness place build great things in mind. And at last it's better to change activities time to time because every activity have it's different aspect of energy levels and experiences and that will help our effective activeness. Thanks for sharing and wishing you an great day. Stay blessed. 🙂
