Advice from Elon Musk
A good framework for thinking is physics.
First principles reasoning.
Boil things down to their fundamental truths and reason up from there as opposed to reasoning by analogy.
We get through most of our life by reasoning through analogy, which essentially means copying what other people do with slight variations — and you have to do that, otherwise mentally you wouldn’t be able to get through the day.
But when you want to do something new you have to apply the physics approach. Physics has really figured out how to discover new things that are counter intuitive, like quantum mechanics.
That’s an important thing to do.
Also, really pay attention to negative feedback and solicit it, particularly from friends. This may sound like simple advice but hardly anyone does that and its incredibly helpful.
