Key mantras:

1. Consistency > Intensity — Study 6-8 hours daily for 1 year
2. Understand > Memorize — UPSC tests understanding, not memorization
3. Revise > New Content — 3 revisions of standard books beat 1 reading of 20 books
4. Newspaper > Coaching — Daily newspaper is more important than any coaching
