I'll begin graduate school next year and I am very impatient to learn new things such as theories, ways of thinking and so on (I enjoyed reading about category theory on my own and I find Galois theory very interesting for example).
However, during my undergraduate - and I am worried that it would do that again in graduate school - I was often stuck because I had to remember old results and/or had to figure out basic things - that I didn't study - (and exemple of this "basic things" can be found in my previous post where I was stuck with a simple set theory equality involving complements) and I find this very hard to manage (in terms of energy and time consumption). When I finally understand what I missed, I am discouraged (it breaks my motivation and I am very tired). Who knows how many of these things I forgot ? What if I have to use one of these tricks during an exam / while learning new material ? How can I better learn to avoid this situation in the future ?
I would like to know how do you react while dealing with similar problem (those who have good - or fresh - memory are not in this position). Do you have a way to quickly find the good reference (except SE) ? Does that break your motivation like me ? If yes, what do you do to "get back on the rails"?
Thanks for your answers.
