If you are grinding through abstract algebra problems late at night, use an e-reader app like Adobe Acrobat or SumatraPDF to invert the document colors to white text on a black background. This prevents eye strain during long proof readings.
Instead of dropping abstract definitions out of nowhere, Herstein motivates them. He heavily leverages the student's existing familiarity with integers and permutations to build the foundations of group theory. By anchoring abstract structures to concrete examples, the abstraction becomes a natural extension of arithmetic rather than an arbitrary set of rules.
