old book on learning question

[Eric Chadbourne]

Probably nobody knows what I'm talking about but...

Many moons ago a mentor gave me a book to read on how to teach yourself.
 It wasn't on any specific topic.  The author may have been a
mathematician.  Maybe written in the 1960's.  Not much to go on.

The other book the same fellow gave me was 'Calculus Made Easy' by
Silvanus P. Thompson.  That book rocked.  What one fool can do, another c=
an.

Thanks for any tips!
