You should do some drawings or origami (the Japanese art of folding paper into various shapes such as swans, whales, flowers, etc.). I like the website Easy Origami Club. There are step by step drawing instructions which let you build your drawing up in layers.
They often have 4 or 5 steps and you can take break in between the steps. I'd also recommend playing a musical instrument.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
