It seems that what a lot of people do is that when they wake up, or they’re stuck in the office or whatever, they try to sit on their butts and try to force themselves to think and come with creative ideas.
I do not believe this to be an effective strategy. Instead, a much more robust strategy seems to be too first walk, walk a lot, and then come up with your creative ideas.
Similarly speaking, a great place to get creative ideas is just going to the gym, the hot sauna, lifting very heavy weights, or even taking very very hot bath at home.
