Sleep on your problems and you will dream the solution. I would say it is also the power to change your environment, go to the nature to get some fresh air, breath and disconnect. Let your imagination bring ideas from different sectors and innovate into your field. Work on the steps to make your dreams come true
“First comes thought; then organization of that thought, into ideas and plans; then transformation of those plans into reality. The beginning, as you will observe, is in your imagination.”Napoleon Hill
Bring innovation to your project, learn from others and different sectors.
