I may be not the only one, but I learned all my practice of working mathematician within the treatise of N. Bourbaki (Theory of sets, Algebra, General topology, Functions of a real variable, Topological vector spaces, Integration, Lie groups and Lie algebras, Commutative algebra, Spectral theories). The front address "To the reader" helped me to use theory, exercises, counter-examples, bibliography. It is a very clear guide (remains to work).
