What's the roadmap to reach nirvana?

Considering I don't know anything about Buddhism expect it leads to something precious called Nirvana, what should be my approach to reach there? From my experience in academics I believe reaching the peak of any field requires strong fundamentals, rigorous training/practice and then creation (ie, invention or discovery of stuff previously non existent or unknown). Does same principle applies here? Is it possible to reach the peak of Budhhist way while being a normal human (who has obligations to fulfill and lives in society) ? Do I need to join a monastery to practice Buddhism?
