Well this depends on your personality taking a world trip is probably fun but the faster you start to learn the faster youl become sucesfull at your career. Personally I would take univarsity first but thats who I am. And my career I want to study for is harder.
Electrical engeneer so it depends on you but I recomend uni.
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.
