How can i get started on studying higher level math again? i got discouraged by proof exercises on the textbooks, i need a fresh start. i feel unmotivated on the subject i thought i loved. how can i motivate myself again? Just about any way to motivate myself would do. also, could i have a list of textbooks on linear, abstract algebra, topology, differential geometry, real/complex analysis. i have realized that the list needs to start easy and FUN then on to the rigorous parts later. But first i need a nice multivariable calculus textbook based on differential forms.
